The Christian faith rests upon a number of foundational truths revealed through Scripture. These doctrines help believers understand who God is, why mankind exists, why salvation is necessary, and what God has planned for the future. This overview is designed as an introduction to the great doctrines of Christianity.
God is the eternal, self-existent Creator of all things. Before the universe existed, God existed. He is not dependent upon space, time, matter, or energy. The Bible begins with the declaration, "In the beginning God created the heavens and the earth."
The Bible reveals God as omnipotent, omniscient, and omnipresent. He is holy, righteous, loving, merciful, and just. These qualities are not separate pieces of God but expressions of His perfect nature.
Creation itself points toward God's existence. The fine-tuning of the universe, the complexity of life, the existence of objective morality, and the reality of consciousness provide evidence that many believe points toward an intelligent Creator.
The highest purpose of mankind is to know God and glorify Him. God desires a relationship with humanity and has revealed Himself through creation, Scripture, and ultimately through Jesus Christ.
Key Scriptures:
Genesis 1:1
Exodus 3:14
Psalm 90:2
Isaiah 40:28
John 1:1-3
Jesus Christ is the central figure of Christianity and the promised Messiah foretold throughout the Old Testament. Christians believe He is both fully God and fully man.
Through His life, teachings, miracles, death, and resurrection, Jesus revealed God's character and provided the way of salvation. His sinless life uniquely qualified Him to become the sacrifice for humanity's sins.
The crucifixion of Christ stands at the center of God's plan of redemption. On the cross, Jesus bore the penalty for sin so that those who trust in Him may receive forgiveness and eternal life.
The resurrection demonstrates Christ's victory over sin and death. It provides the foundation for Christian hope and assurance that those who belong to Him will also share in eternal life.
Key Scriptures:
John 1:1
John 14:6
Romans 5:8
1 Corinthians 15:3-4
Colossians 1:15-20
The Holy Spirit is the third Person of the Trinity. He is fully God and works throughout Scripture to accomplish God's purposes.
The Holy Spirit convicts people of sin, reveals truth, and draws individuals toward Jesus Christ. Without His work, spiritual truth cannot be fully understood.
At salvation, believers receive the indwelling presence of the Holy Spirit. He provides guidance, comfort, strength, and spiritual power for Christian living.
The Spirit also produces spiritual growth, often called the fruit of the Spirit: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control.

John 14:16-17
John 16:13
Acts 1:8
Romans 8:14
Galatians 5:22-23
Human beings occupy a unique place in creation. According to Scripture, mankind was created in the image of God. This does not mean humans physically resemble God, but that they possess qualities such as reason, morality, creativity, self-awareness, and the capacity for relationship with their Creator.
Human beings were created to know God, worship Him, and exercise stewardship over the earth. Unlike the animals, mankind was given the ability to understand spiritual truth and make moral choices. This special status gives every human life dignity and value.
Although mankind possesses remarkable abilities, people are not self-sufficient. Every person experiences limitations, weaknesses, and ultimately mortality. These realities remind us that humanity is created rather than divine.
The Bible presents life as a journey of discovering God's purpose. True fulfillment is not found merely in possessions, success, or knowledge, but in a restored relationship with God through Jesus Christ.
Key Scriptures:
Genesis 1:26-27
Psalm 8:3-6
Ecclesiastes 12:13
Acts 17:26-28
Sin is humanity's rebellion against God. It includes actions, attitudes, thoughts, and motives that fall short of God's perfect standard. The Bible teaches that sin entered the world through Adam's disobedience and spread throughout the human race.
Sin affects every dimension of life. It damages relationships, corrupts societies, produces guilt, and separates people from God. The evidence of sin can be seen throughout history in violence, injustice, selfishness, and human suffering.
The seriousness of sin is measured not only by its consequences but by the holiness of God. Because God is perfectly righteous, He cannot ignore evil. Divine justice requires that sin be judged.
The good news of the gospel begins with an honest recognition of humanity's problem. Before a person can appreciate salvation, he must first understand the reality of sin and his need for forgiveness.
Key Scriptures:
Genesis 3
Romans 3:23
Romans 6:23
Isaiah 59:2
Salvation is God's provision to rescue sinful humanity and restore fellowship with Himself. It is entirely a work of God's grace and is made possible through the death and resurrection of Jesus Christ.
The Bible teaches that salvation cannot be earned through good works, religious rituals, or personal effort. Rather, it is received by faith in Jesus Christ. God's forgiveness is offered freely to all who repent and believe.
Salvation includes several aspects. Believers are justified, meaning declared righteous before God. They are regenerated, receiving spiritual life. They are sanctified, growing in holiness throughout their lives. One day they will be glorified in God's presence.
The ultimate goal of salvation is not merely escape from judgment, but reconciliation with God. Through Christ, believers become children of God and heirs of eternal life.

John 3:16
Ephesians 2:8-9

Titus 3:5
The Bible is God's written revelation to humanity. Composed of sixty-six books written over approximately fifteen hundred years by more than forty authors, it presents a unified message concerning God's relationship with mankind and His plan of redemption through Jesus Christ.
The Scriptures are unique among all books. Although written by kings, prophets, shepherds, fishermen, physicians, and scholars, the Bible maintains remarkable consistency in its central themes. Christians believe that God guided the human authors through the inspiration of the Holy Spirit while preserving their individual personalities and writing styles.
The Bible serves many purposes. It reveals God's character, teaches truth, corrects error, provides wisdom for daily living, and points people to salvation through Christ. Throughout history, countless lives have been transformed by its teachings and promises.
The authority of Scripture rests not upon human opinion but upon God's truthfulness. For believers, the Bible is the final standard for faith and practice. Through careful study, meditation, and obedience, Christians grow in knowledge, wisdom, and spiritual maturity.
Key Scriptures:
Psalm 119:105
2 Timothy 3:16-17
Hebrews 4:12
2 Peter 1:20-21
The Church (ecclesia) is the community of all believers in Jesus Christ. It is not
merely a building or denomination, but the spiritual body of Christ
composed of people from every nation, language, and background who have
placed their faith in Him.
In Ancient Greek, ekklesia (ἐκκλησία) literally means "an assembly" or "a gathering of people called out". It comes from two root words: ek ("out of") and kaleo ("to call").
Jesus established the Church to proclaim the gospel, teach God's Word, encourage believers, and demonstrate God's love to the world. The early Church described in the Book of Acts devoted itself to prayer, fellowship, worship, and the study of Scripture.
Within the Church, believers are given different gifts and abilities for service. Some teach, some encourage, some lead, some show mercy, and others serve in practical ways. Together these gifts strengthen the body and advance God's kingdom.
The Church is called to be both a witness and a light. While imperfect because it is composed of imperfect people, it remains God's primary instrument for spreading the message of Christ throughout the world. Its mission continues until the return of Jesus.
Key Scriptures:
Matthew 16:18
Acts 2:42-47
1 Corinthians 12:12-27
Ephesians 4:11-16
Angels are spiritual beings created by God to serve Him and carry out His purposes. Throughout Scripture they appear as messengers, protectors, worshipers, and ministers to God's people. They are powerful beings but are not divine and are never to be worshiped.
The Bible records numerous angelic appearances. Angels announced the birth of Jesus, ministered to Him after His temptation, strengthened Him before His crucifixion, and proclaimed His resurrection. They frequently appear at significant moments in God's plan of redemption.
Angels are active in both the heavenly and earthly realms. Scripture teaches that they rejoice when sinners repent, worship continually before God's throne, and serve as ministers to those who inherit salvation. Although their activities are often unseen, believers trust that God uses them according to His will.
The study of angels reminds Christians that reality extends beyond the visible world. The universe includes a spiritual dimension where God's purposes are continually unfolding. Yet the focus of Scripture is never on angels themselves but on the God whom they serve.
Key Scriptures:
Psalm 91:11
Luke 15:10
Hebrews 1:14
Revelation 5:11-12
End Times, often called Eschatology, is the study of God's future plans for humanity and creation. The Bible teaches that history is moving toward a definite conclusion under God's sovereign direction. The events of the future are not random but unfold according to His purpose and promises.
The centerpiece of biblical prophecy is the return of Jesus Christ. Christians believe that Jesus, who ascended into heaven after His resurrection, will one day return in power and glory. His return will bring the final defeat of evil, the vindication of believers, and the establishment of God's perfect rule.
Scripture also teaches the resurrection of the dead and a final judgment. Every person will stand before God and give account of his life. For believers, salvation is secure through Christ. For those who reject God's provision of grace, judgment awaits. The justice and holiness of God will ultimately prevail.
The Bible concludes with a vision of a new heaven and a new earth. Sin, suffering, death, and sorrow will be removed forever. God's people will dwell in His presence, and the New Jerusalem will descend from heaven. The final chapters of Revelation present the fulfillment of God's redemptive plan and the eternal hope of believers.
The purpose of prophecy is not merely to satisfy curiosity about the future. It is intended to encourage holy living, faithful service, perseverance, and hope. The promise of Christ's return motivates believers to live with confidence and expectation.
