Paul has spent the first 14 verses telling us how blessed we are because of our place in Jesus: election and adoption.
Being an heir of God is an incredible thing!
You can’t enjoy what you don’t know you have.

It's way more important to understand who Jesus is than who you are.

Because once you truly understand who he is it will shape who you are.
He has heard how they are fulfilling the commandment to love God and love their neighbor. And he has also heard that their faith in Jesus is strong. Shouldn’t that be all he can ask? But, as Paul would say, By no means. He reminds them that they have only begun their journey, and I take comfort in and am encouraged by the fact that given all of that, he knows about the church in Ephesus, still, he prays that Jesus will give them a spirit of wisdom and revelation as you come to know him (Ephesians 1:17).

I don’t just want to start strong, I want a faith that lasts.

The Bible mentions the heart almost 1,000 times. Essentially, this is what it says: the heart is that spiritual part of us where our emotions and desires live.

Finally, Paul mentions that Jesus is the head over the church. Here, we see the amazing connection between Jesus and his church. Only the church, not all creation, is said to be his body. Consequently, the church should be important to us. Jesus literally identifies himself with the church.
WE ARE THE CHURCH!
