"The God who made the world and everything in it is the Lord of heaven and earth and does not live in temples built by human hands. And he is not served by human hands, as if he needed anything. Rather, he himself gives everyone life and breath and everything else." -Acts 17:24-25
At first it sounded as if I am not worthy to be used by Him, but when I came to ponder that statement I found it more of an ultimate compliment to me.
God does not NEED me, God is not desperate for me to follow Him because He has a lot on His plate and needs helping hands; He WANTS me. I am not indispensable to God, but out of His immense love and mercy He is giving me the privilege to be an instrument in His Holy hands and is allowing me to be cleaned, healed, loved, blessed (...) every time I am willing to be used. I can never stand in the way of His work, I can only benefit of His graces through the process.
How soothing it is to know that He is not expecting anything from me, He is not waiting for me to save the world, all He wants is for me to follow Him and to be loved by Him, and then through me, through that process, He will save the world.
