But by a revelation of Jesus Christ

We can lack in no gift, but lack the revelation of Christ. When it please God, you can be chosen, you can receive grace, or Christ can be revealed. Some done believe - they are not sheep. For some the gospel is hidden - they are lost. Some don't find the gate of life - they are on the broad way. Some are from the world - they cannot receive the Spirit. Some don't understand - their father is the devil.
