The grace of God!
"But by the grace of God I am what I am!" 1 Corinthians 15:10
The grace of God, which provides, reveals, and effectually applies all the blessings of salvation — teaches, motivates, and sweetly compels saved sinners to devote themselves to Christ. Believers are not ruled by law, but by grace.
"For sin shall not be your master, because you are not under law, but under grace!" Romans 6:14
