'Mature' in the Bible

Since I am convinced of this, I know that I will continue to live and be with all of you, so you will mature in the faith and know joy in it.

Not that I have already reached the goal or am already fully mature, but I make every effort to take hold of it because I also have been taken hold of by Christ Jesus.

Therefore, all who are mature should think this way. And if you think differently about anything, God will reveal this also to you.
