Christ finished salvation. He died for the sins of the whole world. Eternal life is a gift… The gift is free; all we have to do is accept it or reject it, take it or ignore it. We must be like one or the other of the thieves on the cross: either believe that Jesus is God and can save a sinner who acknowledges his sinful condition, and spend eternity with Christ in paradise, or be like the other thief and disbelieve that Jesus is God, and die in our unrepented and unforgiven sins, away from God.
