It is an encouraging and emboldening truth to know that God uses the weak and insignificant people of this world to expand his kingdom. God has uniquely chosen the foolish to shame the wise in this mission to exalt his name. Such is what Paul says to the Corinthians in his first letter to them. It is God’s prerogative to assign the great mandate of the Great Commission to frail, feeble creatures like us. 3rd John speaks to this point excellently, showing both God’s gracious choice of us and our function as his children.
