How do we know it is through grace that we are saved?

The certainty of salvation by grace is firmly rooted in Scripture. Acts 15:11 clearly articulates that salvation comes through the grace of the Lord Jesus Christ. Furthermore, Romans 3:20 tells us that 'by the deeds of the law, there shall no flesh be justified in His sight.' This unmistakable message throughout the New Testament underscores that our salvation is not based on human works but on God's sovereign grace. The critical event of Christ’s sacrifice, as highlighted in Ephesians 2:8-9, assures us that it is by grace we are saved through faith, which is not of ourselves; it is the gift of God.
