It is an offense against holy God to choose not to trust Him. Ultimately there will be consequences for not believing Him.
We live in a society and an age when people have largely chosen not to place their trust in God. They have heard the Gospel. They know what God says. But they have refused to believe it. Instead, they have pursued their pleasures and trusted in themselves or in others in order to have their needs met. Some have brazenly mocked the claims of God and openly despised His word.
History is clear that God will only be patient so long with those who reject Him. Inevitably He will allow such people to reap what they have sown. Those who reject His salvation will eventually perish, even as they futilely grasp at their idols. A time eventually comes when God exposes us, and our pitiful beliefs, for what they are. If His loving provision and forbearance will not bring us to faith, then He will judge us and cause us to bear the full weight of our foolish choices. A day is coming when each person will experience the full consequences for having refused to trust in God.
