How do we know that Christ is sufficient for our salvation?

The Bible attests to the sufficiency of Christ in multiple passages, highlighting that He is the way, the truth, and the life (John 14:6), emphasizing that no one comes to the Father except through Him. Paul illustrates that Christ is not only the means of salvation but also the fulfillment of the covenant promises made to His people. As believers, we receive Him as our Lord and Savior, recognizing that through His life, death, and resurrection, He has secured our redemption from sin, the law, and eternal judgment. Trusting in Christ's finished work guarantees not only our justification but also empowers our sanctification, allowing us to live in the fullness of His grace.
