How could God use me? How can He possibly use somebody with so many weaknesses? God doesn’t look at it like that. He has a place for us, and has gifted each of us accordingly. So bloom where you’re planted, no matter who you are or what insecurities you may have.
Even a guy like Paul had his problems. It appears that somewhere along the line God needed to reduce him to a point of utter helplessness. Why would He do that? Because in order to be effective, Paul had to be a vessel capable of radiating God’s power.
Since it’s impossible for God to work through a prideful vessel, human weakness seems to be necessary. Apparently God wants us in a state of total dependence on Him, rather than on our own abilities. Jesus puts it this way: “My grace is sufficient for you, for power is perfected in weakness.” (2 Cor 12:9)
