Every human is of worth to God. We are His creation. And each of us is "fearfully and wonderfully made." God thought so much of each one of us that He gave a supreme sacrifice that every person could have the opportunity to have the gift of salvation.
God uses ordinary people to accomplish extraordinary things. I have seen God provide healing to a critically ill person after ordinary people petitioned God in prayer. And he wants to use you too.
So what steps can you take to begin to uncover your God-given purpose?
