What does the Bible say about faith in Christ's ability?

The Bible teaches that faith is fundamentally about believing in Christ's ability. For instance, in Matthew 9:27-31, two blind men express their faith by acknowledging Jesus as the Son of David and seeking His mercy, demonstrating their belief in His power to heal them. Similarly, Romans 4:20-21 illustrates Abraham's faith, which was rooted in his conviction that God was able to fulfill His promises despite his circumstances. This theme reoccurs throughout Scripture, asserting that God's omnipotence enables Him to accomplish what He has promised, and true faith recognizes and rests in that ability.
