How does faith relate to the sufficiency of Christ in salvation?

Faith serves as the critical link between believers and the sufficiency of Christ's work. It is through faith that we grasp the reality of what Christ has accomplished on our behalf—His perfect life, sacrificial death, and triumphant resurrection. Romans 10:17 teaches us that faith comes from hearing, suggesting that an understanding of the gospel leads to believing in the sufficiency of Christ. Without this faith, we cannot experience the full assurance of salvation that comes through knowing that Jesus is all we need for a restored relationship with God. Thus, faith is not merely intellectual assent but a heartfelt trust in the completeness of Christ’s redemptive work.
