Finding Your God-Given Gift
You may think your God-given gift is a special talent in writing, music, art, etc. A special talent is something you excel at. You either practised all your life to become the best, or it just came naturally to you - like God made you for that particular purpose.
Or, your God-given gift could be what you like to do the most in life, what you enjoy doing more than anything. In truth, that could also be closely aligned with your talent. I loved singing and had a powerful soprano voice, so when I felt led into a singing career it seemed natural to do so. When I came to the realization that perhaps God gave me the gift of singing to glorify Him and spread the Gospel, I used my voice for Him, rather than for my personal gain.
Now, you will notice that I have not talked about Spiritual Gifts. There is a reason for that. These gifts are given when we are baptized in the Holy Spirit. But, God-given gifts are different in that they have been with us since before we were born.
