There are those near you in your own community who need the regenerating power of Christ. You can call them by name. I suggest that you make a list and begin by spending time in prayer for them. Ask God to show you how to witness to them and how to win them. Their lives can be transformed by the message you give them. You are to share this Gospel you have received. If Christ has done anything for you, then share it. In so doing, you are showing mercy! As you have received the mercy of God by the forgiveness of sin and the promise of eternal life-thus you are to show mercy! And in showing mercy you will not only receive mercy but you will find a stimulating happiness!
