As Christian people, we need to be mindful of the lost. They could be going to your church, your school, your grocery store, really anywhere in your daily life. We need to be mindful of them and witness to them. The best people to talk to are the people you already have a relationship. Your circle is easier to witness to, then going up to a stranger and trying to witness. You develop a trust and understanding with people in your circle. You don't "have to" do anything in your Christian life, you "get to" do things. NO ONE says "I have to go to Heaven", everyone pretty much says "I want to" or "I get to" go to Heaven. We should be trying to reach to other people, so they can get to go to Heaven also.
