Think on the LB thought of the day. Where it says God opened the heart of Lydia to heed the instructions of Paul. What an amazing woman she must have been to have God stirring in her life before even knowing Jesus.
God is working in the lives of the unsaved for the express purpose of bringing the message of the Gospel to them.

Now consider this, Paul was the intended person God told her to heed. What if he hadn't gone? What if there is a friend or loved one of yours you haven't witnessed to that God intends to bring them to Jesus through your teaching, your words, but you don't go.
