When Jesus fed the crowd of 5,000 in Mark 6:33-44, He did four things. 1) He took the bread and the fish, 2) He blessed the food, 3) He broke the food and 4) He gave the food to the multitude (see verse 41). This is how God works with us. He takes us, He blesses us, He breaks us and then He shares His life through us.
If you want to be used by God, you cannot skip the third step. We love to be blessed, but few of us want to be broken. But if you have not been broken you cannot reach your full potential. Your influence will be determined by how much you allow the brokenness of God in your life. God uses trials and difficulties to form your character. Embrace your trials and let God shape you. Submit to His dealings. In the end, your life will touch a multitude.
