Most of us will never leave home and country and change our names; but that doesn’t mean that we can’t make radical, intentional, life-altering decisions. Sarai accompanied Abrahm when God called him to leave his home and country. She stood by his side and converted pagan women to the one true God as Abrahm converted men. She did it out of complete faith in God. She became Sarah and he became Abraham.
We, too, can become a light to others simply by trusting that God is using us in whatever circumstances we happen to be in. We may not change our names or where we live but that shouldn’t stop us from be drastically different when we freely choose to follow God.
