There isn't much I can add to what Blackstone has already said to answer this question. However, here is something that is related to the question. Some Christians (myself included...I've done this too...) sit around and wonder what they should be doing for God. "What is my calling or my gift or whatever?" Well, here is an easy answer to all of that. Do whatever you can see that needs to be done. Do you have next door neighbors who are elderly and maybe they need help getting to the store or need things done around their house? Is there someone you know who is hurting in some way who really needs a friend who will come alongside him without judging him? Are there poor and needy people in your community who need help? The whole world around us is filled with opportunities to be Jesus to people, all we need to do is open our eyes and ears and be willing to jump in and do what Jesus would do....or want us to do.
