The New Testament is clear that we ought to be not only sharing the gospel, but serving others so they are open to hearing from us. Some Christians/churches focus on service alone and never share Christ with people. Although they may have helped the body, they have neglected the soul. Others are vocal and telling others about Christ but are negligent in serving people. I think people need to both see and hear the love of God. As we serve others, the door often opens so we can share (see 1 peter 3:15). So, how are you doing with this delicate balance? Do you need to serve more or share more? God help us to be positive influencers for those who have yet to come to know Him.
