How do we know that Jesus Christ's work is sufficient for our confidence before God?

The sufficiency of Christ's work for our confidence before God is affirmed in Scripture, particularly in passages like Hebrews 10:19-22. Here, the author emphasizes that it is through Christ's sacrifice that we gain boldness to enter into the presence of God. This demonstrates that our salvation is not contingent upon our works but is based solely on Christ's completed work. Believers can approach God confidently, assured that all necessary provisions for salvation and favor have already been met by Jesus. This impartial and finished work provides the security we seek in our relation with God.
