Salvation is God's gracious work not ours

"We do not contribute anything to our salvation, even our faith is the free gift of God, which passively receives and appropriates the imputed righteousness of Christ alone. It is the only object of our faith which justifies us before God - never the act of faith. The only object of our faith is the Gospel of Jesus Christ alone, the saving Gospel promises. Again, the object of our faith is not our works or anything in us, for we are justified by an alien righteousness, the covering righteousness of Christ alone." - Monty L. Collier, A Unique Kind of Righteousness, pg. 5
