What does the Bible say about faith?
The Bible presents faith as the defining response to the gospel of Jesus Christ—but not merely as mental agreement or private belief. Biblical faith is active, embodied, and loyal. It is not reduced to acknowledging theological facts; rather, it involves a whole-life commitment to Jesus as Lord. From Genesis to Revelation, faith is shown as trust in God's promises and allegiance to His reign.
The call to faith in the Bible always involves movement: turning away from sin, embracing the kingdom of God, and living under the authority of Christ. This article explores what the Bible says about faith, how it relates to discipleship, salvation, the Gospel, and the kingship of Jesus.
1. Faith in the Bible Means Loyal Trust in Christ the King
One of the clearest teachings in the Bible is that faith is a response to the announcement that Jesus is King. In Mark 1:15, Jesus begins His ministry saying, “The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel.” The gospel is not merely about escaping punishment—it is the declaration of a new reality under Christ’s reign.
True faith, then, involves repentance and belief—turning from sin and pledging allegiance to Jesus. This is not blind faith, nor is it just intellectual. It is personal trust and covenant loyalty. The kingdom of God confronts all rival allegiances, calling each person to reorient their life under the authority of Christ.
Throughout Scripture, the call to believe is never detached from the call to follow. Faith that is biblically grounded recognizes Jesus not only as Savior but as Sovereign. He is not merely the one who forgives; He is the one who rules.
2. Faith Is Expressed in Obedience and Action
The Bible teaches that faith is visible in action. As James 2:17 puts it, “So also faith by itself, if it does not have works, is dead.” This does not mean faith is earned through effort, but that living faith naturally produces fruit. Obedience flows from trust.
Hebrews 11, often called the “hall of faith,” is filled with examples of men and women whose trust in God moved them to act. Noah believed God—and so he built an ark (Hebrews 11:7). Abraham believed—and so he left his homeland. Rahab believed—and so she welcomed the spies. Faith always steps forward.
In Ephesians 2:8–10, Paul clarifies that salvation is by grace through faith—and this faith leads to good works prepared by God. Biblical faith reshapes every area of life. It is not passive or abstract; it is loyalty lived out in public and personal obedience to Christ’s commands.
3. The Kingship of Jesus Is the Object of Saving Faith
In the Bible, saving faith is inseparable from the identity of Jesus as King. The gospel message is not simply that Jesus died and rose again, but that He was enthroned through His resurrection. Philippians 2:9–11 declares that God exalted Christ and gave Him the name above every name, “that every knee should bow…and every tongue confess that Jesus Christ is Lord.”
Even forgiveness of sins is grounded in Jesus’s authority. As the King, He has the right to pardon—and baptism becomes the visible declaration of this allegiance. Baptism is not just about personal cleansing; it’s about publicly identifying with the kingdom of God. Faith receives Jesus not only as the one who saves from sin, but as the one who reigns in righteousness.
To follow Jesus is to submit to Him. The Bible’s vision of faith is deeply political—it dethrones the idols of the world and enthrones Christ. Biblical faith bows the knee and joins the Kingdom.
4. The Thief on the Cross Shows the Heart of True Faith
The example of the thief on the cross (Luke 23:39–43) illustrates the heart of kingdom-centered faith. As he hung beside Jesus, he acknowledged Him, not merely as an innocent man, but as the King: “Jesus, remember me when you come into your kingdom.” His request wasn’t abstract belief—it was a recognition of royal authority.
Jesus’s reply—“Today you will be with me in paradise”—shows that faith is not about merit or time served, but about trusting in the one who rules from the cross. Even in his final hours, the thief believed that Jesus was enthroned, and that this crucified Messiah had the power to save.
This scene challenges modern ideas that faith is just mental assent or emotional sentiment. It reorients us to the biblical truth: saving faith confesses Christ’s kingship. It may come in a moment, but it always points to a new allegiance.
5. Faith Is the Beginning of Discipleship and a Kingdom Life
The final command of Jesus in Matthew 28:19–20 is a call not merely to make converts, but disciples: “Go therefore and make disciples… teaching them to observe all that I have commanded you.” This shows that faith is the start of a lifelong journey of learning to live under Christ’s rule.
In the Bible, discipleship is the context where faith matures. The church is not simply a place to confess beliefs—it is the community where allegiance to King Jesus is taught, practiced, and sustained. Through worship, teaching, and mutual encouragement, the people of God grow in faith and are shaped into a reflection of His kingdom.
Faith does not end with a moment of belief—it deepens through obedience, service, and communion. It confronts selfishness and cultivates humility. It resists the world’s ways and pursues the way of Christ. In this way, biblical faith is the entrance into a new life—and a new kingdom.
Conclusion: Biblical Faith Is Allegiance to Jesus as King
What does the Bible say about faith? It says that faith is not simply believing in a doctrine, but bowing to a King. It is the surrender of the whole self to the reign of Jesus, trusting not only in His death and resurrection but in His ongoing rule.
Biblical faith is covenantal, loyal, and active. It leads to obedience, it grows in community, and it bears fruit. It is faith that transforms, not just saves. It is faith that steps into the story of the Gospel—a Gospel that announces a kingdom, not just a personal rescue.
To have faith is to trust Christ with all that you are—to believe the Gospel, live under His lordship, and await the day when every knee bows before the throne. Until then, faith lives, worships, and works as a citizen of a better Kingdom.
