This promise from the Lord has given me comfort many times when I have felt blunt and dull through my own sinfulness or fatigue. God has used this Scripture passage to remind me that He can instantly transform me into a new and effective instrument for Him despite my previous poor performance.
Jesus lifted His disciples at a mundane point in their lives – as they were fishing – and said, “Come, follow me and I will make you fishers of men.” He lifts their efforts to an entirely different and thrilling plane. They could never have dreamed that they would be used by God for such an elevated purpose. David could never have guessed God would pick him, a shepherd boy to be King of Israel. And God knows what instrument of service He has in mind for you!
