#1) Ephesians 2:8
"For by grace you have been saved through faith; and that not of
yourselves, it is the gift of God."
Grace is the tenet of Christianity that separates it from all other
faiths. It is by grace that we have eternal life.
It is all God's doing, not ours. Salvation is a gift from God, and
verse 9 goes on to assert that it is not by any works that man can
do. We can only accept God's free gift of grace, through the sacrifice of Jesus Christ on the cross.
Grace is free (2 Corinthians 8-9). It's given to us freely by
God, and nothing we can do could earn what He gives us (Isaiah
64:6). 2 Peter 3:18 commands us to "continue to grow in grace." Just
as God has freely showered us with His grace, our lives should reflect His
grace to others.
