How can we be sure that we believe the witness of Christ?

To genuinely believe the witness of Christ is to acknowledge Him as the central figure in God’s redemptive plan and to trust in His works for our salvation. This belief is not merely intellectual assent but a deep-seated faith that transforms the heart and life. Jesus points out that those who truly hear Him and understand will be drawn to Him. This belief is also evidenced by the fruit of faith in our lives—an ongoing repentance from sin, a desire for holiness, and a love for God and others. Ultimately, the assurance of our belief comes from the indwelling of the Holy Spirit, who confirms our faith and continually points us to Christ as our sufficiency in all things.
