“When the wicked die, their hopes die with them, for they rely on their own feeble strength.” (Proverbs 11:7)
I don’t really need to add anything here. Those who only rely on their own skills and abilities to accomplish something will fail in the end. They’ll die (as everyone does, sooner or later) and their plans will die with them.
But those who put their trust in God and strive to do as he asks will succeed. And more than that, their plans will continue: if it is God’s way.
