Scripture: from verses 16 and 17
I pray that from the treasures of His glory He will empower you with inner strength by His Spirit, so that the Messiah may live in your hearts through your trusting.
Observation: So. The goal of this prayer is for the Messiah to live in our hearts. Two things are apparently required for that to happen: for us to trust, and for us to have inner strength. I’m not certain why we need inner strength in order for Messiah to live in us, but I guess it’s because Messiah changes us, and we need the strength to cooperate with those changes and not turn away. The Holy Spirit gives us the strength we need from the treasures of God’s glory. Possibly because God is strong, possibly because God made me and has the ability to upgrade me, and possibly because the reward of God’s glory helps us be strong. Though I’m disinclined to believe that last one, since it assumes we have the strength on our own, and we don’t.
Application: Trust in Him, since apparently there’s not much else we can do. Use the strength He gives us.
Prayer: Holy Spirit, please empower me so that Yeshua can live in my heart. Please give me the courage to belong to Him. Amen.
