It's funny that I was just talking about this yesterday, the Spirit of God is something that has been preparing for us to receive. Paul says in 1 Corinthians 2:2
"for I decided to know nothing among you except Jesus Christ and Him crucified."
He decided to know nothing, he was nothing and made himself weak to demonstrate the power of the Holy Spirit living in him. When we are with the Holy Spirit living and filled, we are not of our own strength, we don't need to be of our own strength, it is by the power of God that we will breath and move with boldness. Paul didn't rest knowing wisdom on his self, but surrender allowed the power of God to be demonstrated. Our job is surrender. We must be less and He must become more and through that, power is demonstrated through us. Pay attention to this truth. God kept this wisdom for us, He saved it for us, He held this power to be used by us when we come to Christ and receive it.
