Verse 25 says that the foolishness of God is wiser than men and the weakness of God is stronger than men. Have you ever been called foolish by someone because you have accepted Jesus as your Saviour and are now born again? Don’t worry about it if this has happened because it says in verse 27 says that God has chosen the foolish things of the world to confound the wise.
God will use us, foolishness and all if we yield our lives to him. God is not so interested in your ability as He is un your availability. You can have all the ability to do everything in the world, but if you are not available, then what good is your ability? It is of no use to God. If you have accepted Jesus as your Saviour, don’t worry about what others think. That is not important. What God thinks is most important. He will use you if you make yourself available. Live to please Him and not people.
