Ephesians 3:15-17

from whom his whole family in heaven and on earth derives its name.

(v15, NIV)

God is our creator and from him each and every person is created. Paul bows before the Father, and it is this same Father who is father of each and every person on heaven and on earth.

I pray that out of his glorious riches he may strengthen you with power through his Spirit in your inner being,

(v16, NIV)

God has the ability to strengthen us. We are also told where this power comes from or rather its magnitude. It is according to the riches of his glory. God has received and deserves all glory and honour and praise. As such, his glory is massively big beyond words can describe. According to this is where this strengthening is coming from. This strengthening isn't simply an outward physical thing. It is through his Spirit in our inner being. The strengthening is something inward and not something outward.

so that Christ may dwell in your hearts through faith. And I pray that you, being rooted and established in love

(v17, NIV)

This strengthening is required in order that Christ may dwell in our hearts through faith. In order for Christ to dwell in our hearts through faith, we require this strengthening that is mentioned in verse 16. The through faith part is how we are saved and mentioned in chapter 2 verse 8. We are saved by grace through faith.

P.Kai at Oasis preached a sermon on the gospel. In preparation for this sermon, he said a few things in preparation and hinting to the congregation. One question he asked was for the congregation to find in the bible where it tells us to ask Jesus into our hearts. It is not in the bible. Here, verse 17 is the closest thing to asking Jesus into our hearts. But really, it should be described as the living out or living through Jesus. For Christ to dwell in our hearts is for us to live for Jesus and for Jesus to live through us. Our heart's desire and yearning should be solely focused on Jesus and his death and sacrifice on the cross.
