This is probably the most common question asked in connection with gifts. I always respond with, “What do you enjoy most about serving the Lord?” Notice, I don’t ask, “How are you serving the Lord?” I am interested in what they enjoy doing. You will look forward to the responsibilities you are given that call on you to use your gift. On the other hand, you will not be as motivated for tasks that are outside your giftedness.
When we minister to others through our gifts, we are tapping into the inexhaustible energy and motivation of God. When we exercise our gifts, the Holy Spirit works through us. We experience an extra measure of energy and joy.
Serving outside our gifts is a different story altogether. I believe this is the primary reason so many Christians get burned out on church work. Instead of finding a position where they can use their gifts, they sign up for whatever task is available. They do their best as long as they can take it, then they quit.
You can take spiritual gifts tests. But probably the best way to discover your gift is to serve in a variety of ministry situations. When you find the area that suits your gift, you will know it.
