When individuals in a congregation do not know what their spiritual gifts are, they cannot grow to their full potential, nor can the church. In fact, a church cannot successfully meet needs of the church or the community if every member is not using their spiritual gifts to serve others. Discovering our spiritual gifts is probably the second most significant spiritual experience we will ever have. The first is, of course, accepting Christ as our Savior. Romans chapter 12 is a great scripture that teaches the importance of Spiritual gifts.
Spiritual gifts are to serve others.
Christ came to serve others, thus we are fulfilling the work of Christ and carrying on Kingdom work through our spiritual gifts. The First Baptist Church of Modestor, TX discovered Spiritual gifts in 1967. They reorganized their activities and structured their congregation differently than it had traditionally been. Then, their members discovered their Spiritual gifts and began using them to bring more people to Christ. You are waiting for the results aren't you.
