Many of your friends are wandering around lost. They don't know God because no one has told them that Jesus loves them. No one has told them they need to accept His free gift of forgiveness and ask Jesus to come into their hearts. God is always with you when you tell others about Jesus. The Bible is God's Word. In His Word, He points the way you should go and what to say to others about Him. We can help those who are wandering around in the world without the hope and love of Jesus in their heart.
We should remember, someone loved us enough to point us in the right direction. God wants us to share the message of Jesus. He places His love in us when we are saved. Telling people the "good news" about Jesus and how much He loves them is call "sharing the gospel." Sharing the gospel is sharing God's love.
