I believe we are the living conduit of everything God desires to do in this world, and everything we do and say is important. We might do good, we might do bad, or we might do what seems to us inconsequential, but in God’s eyes and for His purpose, everything we do and say, He will use toward His ultimate goals. There are no accidents.
I am convinced that each of us is on this earth to serve God, and we will do so willingly or, in some cases, unwillingly. One might think himself to be a nonbeliever, refusing to even acknowledge God, but even in so doing, he is ultimately contributing to the will and purpose of God.
As every man hath received the gift, even so minister the same one to another, as good stewards of the manifold grace of God. 1Peter 4:10
