God's grace is seen in Christ Jesus. God sent his only Son to die for those who rebel against him. The perfect one was punished. The imperfect are set free. God's grace is complete.
Salvation is a done deal.
His word is final. God's grace is eternal. Think about it. To answer that question we don't look to ourselves, our lives, or even our faith. Rather, we look to our gracious God, who has always loved us for no other reason than that he chose to love us.
