“Go home to your friends and tell them how much the Lord has done for you, and how he has had mercy on you.” This was the command Jesus gave to a man that was saved and set free from thousands of devils! And its the same command He's have given you and me!
Your story matters! Your encounter with God's saving grace and His redeeming power will help bring others into a saving knowledge of Christ! Don't ever be afraid to tell your story of God's love. It's too important!
