God does not take back the gifts once he gives them to you. You can use them at any time, although they are empowered supernaturally through the Holy Spirit, they are subject to you. You can start and stop at anytime with your free will.
Have you ever wrestled with knowing who you truly are? Is your mind invaded with insecure thoughts surrounding your identity? Do you find yourself lacking peace and feeling shame and guilt? If you are constantly thinking that you are not good enough, insignificant and incomplete, then 'God, Who Am I?' is for you!
I am in this world, but I am not of this world. You, Lord, are all I have, and you give me all I need; my future is in your hands. -Psalm 16:5
