"I planted, Apollos watered, but God gave the growth."
There's something quite humbling about that statement, and quite freeing too. There's no sense in assigning honor to God's men because of what seems to be happening as a result of their labor--it's all God's doing. Then could one surmise that the workers are nothing, just pawns in God's game of redemption? Not at all! That's not it either. Paul calls God's laborers "fellow workers".
The wise worker builds upon the foundation of Christ, which assumes that growing God's people to maturity doesn't move them away from the foundation to some sort of "higher knowledge", but rather to fuller dependence upon Christ. To do otherwise is short sighted and even destructive.
In the end, the counsel for all is this: become a fool for Christ. Know that God has accomplished and given all in Him alone.
Increasingly I am believing this with my whole being. I'm part of the church planting culture, by virtue of being a church planter. Guys are always looking for the next bit of insight or wisdom that will allow them to grow a church or increase its impact. For the most part their heart is in the right place. They want to see Christ Jesus lifted up. But is there any weapon more powerful than the gospel, which is the "power of God unto salvation?"
