It’s by Grace (God’s Righteousness At Christ’s Expense) that we ARE saved through faith, and that NOT of ourselves (anything we have done) it is THE GIFT of God. The same Grace that saved us is the same Grace that sustains us as we walk out and work out this salvation. Ephesians 2:8-10, John 1:16-17, Philippians 2:12-13, Titus 3:5.
