If God says, "What is that in thine hand?" let us examine honestly if it is something He can use for His glory or not. If not, do not let us hesitate an instant about dropping it. It may be something we do not like to part with; but the Lord is able to give us much more than this, and the first glimpse of the excellency of the knowledge of Christ Jesus the Lord will enable us to count those things loss which were gain to us. But if it is something that He can use, He will make us do ever so much more with it than before.
Moses little thought what the Lord was going to make him do with the "rod in his hand"! Henceforth it was "the rod of God in his hand."
