How do we know the grace of God is sufficient for salvation?

The Bible asserts that the grace of God has been manifested in Jesus Christ for the salvation of all mankind (Titus 2:11). This grace is not based on human merit but solely on God's mercy and love. In Ephesians 2:8-9, we learn that salvation is by grace through faith, showcasing that it is a gift from God, not something we can earn. Moreover, the New Testament consistently emphasizes that Jesus' sacrificial death and resurrection are the fulfillment of God's redemptive plan, offering a way for sinners to be reconciled to Him. This assurance lets believers rest in God's grace as they await the glorious return of Christ, reaffirming the sufficiency of His work for their salvation.
