What is the difference between the grace of God and the mercy of God? Someone has defined it this way. Grace, is God giving to us what we do not deserve; righteousness, peace and pardon (Romans 3:24; 6:23). Mercy, is God not giving to us what we do deserve; wrath, death and eternal punishment (Titus 3:5). Thank God for His eternal, sovereign grace and mercy; revealed and experienced in the heart of the sinner in Christ Jesus the Lord (II Corinthians 4:6)!
