That got me thinking. God has made other promises since the Flood. For instance, he promises to save from eternal punishment those who repent and believe Christ. But what sign is there that God will do what he has promised? Until death comes, how can a Christian be confident that he will escape the punishment he rightly deserve for his sins?
Perhaps the greatest sign is the change God makes in a believer’s life (2 Cor. 5:17). His change in thinking and his longing to please the Lord are evidence that God has converted him as promised. This “sign” is evidence that God does do what he promises. And since God has so evidently kept that promise, how can a Christian doubt that God will keep the other promises as well?
