There are many mysteries mentioned in the Bible. A mystery can be used to ways. It reveals something that was hidden before, or it may be a supernatural state - known to be true, yet remains incomprehensible. This is one of those cases. God promises that we have everything we need to live a life like Jesus. I have everything to make the Fruit of the Spirit my character. To live a life as it should be lived. And this is mine through my personal, individual, growing relationship with God.
