The 16 Fundamental Truths serve as the theological backbone for our faith community, providing a clear, scriptural roadmap for our journey with Christ. These doctrines define our understanding of God’s nature, the Holy Spirit's power, and our eternal hope. They ensure we remain rooted in the Word while growing together in grace and truth.
Key Scriptures for Our Study
"All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work." : 2 Timothy 3:16-17
"But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth." : Acts 1:8
"For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life." : John 3:16
Understanding the Foundation of Our Faith
Welcome home! I am so glad you are here to dive deep into the Word with us. If you’ve been searching for a place where you are never forgotten, never alone, and always deeply loved by God, you’ve found it. As we embark on this Bible study, it is vital to have a clear understanding of what we believe and why we believe it. In a world full of shifting opinions, having a firm foundation is everything. The Assemblies of God worldview IS the guardrails.

These 16 Fundamental Truths aren't just a list of rules; they are a celebration of God’s character and His plan for your life. We categorize these into four "Cardinal Doctrines" that are essential to our mission: Salvation, the Baptism in the Holy Spirit, Divine Healing, and the Second Coming of Christ. Let’s look at how these truths shape our daily walk.
1. The Inspired Scriptures
We believe the Bible is the inspired Word of God. It is our ultimate authority for faith and conduct. When life gets confusing, we don’t look to culture for answers; we look to the Word. It is infallible and completely sufficient for guiding your life today.
2. The One True God
God has revealed Himself as the eternally self-existent “I AM.” We believe in the Trinity: the Father, the Son, and the Holy Spirit. He is the Creator of all things and the Redeemer of mankind, inviting us into a personal relationship with Him.
3. The Deity of the Lord Jesus Christ
Jesus is not just a "good teacher." He is the eternal Son of God. We affirm His virgin birth, His sinless life, His miracles, His substitutionary work on the cross, His bodily resurrection, and His current exaltation at the right hand of God. He is fully God and fully man.
4. The Fall of Man
Man was created good and upright, but through voluntary transgression, we fell into sin. This fall brought both physical and spiritual death, creating a separation from God that we cannot bridge on our own.

5. The Salvation of Man
This is a Cardinal Doctrine. Salvation is found exclusively through Jesus Christ. There is no other name by which we must be saved. By repenting of our sins and placing our faith in Jesus, we are justified by His grace. It is a gift: you can't earn it, but you can receive it freely. We reject universalism; the only path to the Father is through the Son.
6. The Ordinances of the Church
We practice two main ordinances: Water Baptism by immersion and Holy Communion. Baptism is a public declaration that we have died to our old selves and are raised to new life in Christ. Communion is a symbolic remembrance of His suffering and death for our sake.
7. The Baptism in the Holy Spirit
This is our second Cardinal Doctrine. We believe all believers are entitled to and should ardently expect the promise of the Father: the baptism in the Holy Spirit. This experience brings an endowment of power for life and service, enduing us with gifts to reach the world.
8. The Initial Physical Evidence
We believe the baptism of believers in the Holy Spirit is witnessed by the initial physical sign of speaking with other tongues as the Spirit of God gives them utterance. This is a beautiful, empowering gift for every believer.
9. Sanctification
Sanctification is an act of separation from that which is evil and a dedication unto God. It is both an immediate position at salvation and a progressive lifelong journey of becoming more like Jesus through the power of the Spirit.

10. The Church and Its Mission
The Church is the Body of Christ. Our mission is fourfold: to evangelize the world, to worship God together, to build up a body of believers being perfected in the image of Christ, and to demonstrate God’s love and compassion to a hurting world.
11. The Ministry
God calls men and women to lead and serve the Church. This divinely called ministry is provided to lead us in worship, build up the saints, and ensure the Great Commission is carried out across the globe.
12. Divine Healing
This is our third Cardinal Doctrine. We believe that deliverance from sickness is provided for in the atonement and is the privilege of all believers. God still heals today, and we pray with boldness for the sick to be made whole.
13. The Blessed Hope
The fourth Cardinal Doctrine is the Second Coming of Christ. We look forward to the resurrection of those who have fallen asleep in Christ and their translation together with those who are alive and remain. This is the "Rapture," our great hope!
14. The Millennial Reign of Christ
The second coming of Christ includes the visible return of Christ with His saints to reign on earth for one thousand years. This reign will bring the salvation of national Israel and the establishment of universal peace.

15. The Final Judgment
There will be a final judgment in which the wicked dead will be raised and judged according to their works. Anyone whose name is not found written in the Book of Life will be consigned to everlasting punishment. This truth reminds us of the urgency of our mission to share the Gospel.
16. The New Heavens and the New Earth
Finally, we look forward to the "new heavens and a new earth wherein dwelleth righteousness." We will live eternally in the presence of God, where every tear is wiped away and all things are made new.

A Prayer for Your Journey
Heavenly Father, thank You for Your Word which is a lamp to our feet and a light to our path. As we study these fundamental truths, open our hearts to understand Your character more deeply. Strengthen our faith, empower us by Your Spirit, and keep us focused on the blessed hope of Your return. Let every person reading this feel Your overwhelming love and presence today. In Jesus’ name, Amen.
