Knowing the bible does not mean you can open a church and start ministering. You can be called but not yet ready to be commissioned. John 7:6 Then Jesus said to them, “My time has not yet come, but your time is always ready. Knowing what He can do, Jesus was able to say “No”.
Jacob was ordained a leader from birth but her mom still tried to use shortcut to her calling. Genesis 25:23 And the LORD said to her: “Two nations are in your womb, Two peoples shall be separated from your body; One people shall be stronger than the other, And the older shall serve the younger.”
There are people who are called but because they can’t wait to be properly commissioned end up acting their calling and in the process hurting God’s people. It’s not that they are not called but they are not ready for the work. These people end up trying to imitate other man and woman of God.
Matthew 22:14 “For many are called, but few are chosen.”
