Leighton Vary, with a simple but powerful breakdown of Ephesians 1:3-14. Here is how he concludes:
All in all, we can look at this passage in one of three ways: We can see how much we are blessed, we can see how amazing God is, or we can see both. If we look at this from only the first perspective, it puts the focus on us, and we can easily distort this to say that we are the center of God’s attention. If we focus on only the second, then we miss out on the amazing blessings that come from a life given to God. But if we focus on the third, then we see that God blesses us for the purpose of bringing himself glory. God’s main concern is with his own glory, but that is the best thing for us as humans. Even in blessing us, God is still the center of the story, not us.
I am completely in awe about how much God does, and how much he does for me. There is (gloriously!) not enough time in this life to mine the wealth of wonder and truth out of this passage alone, let alone the vast canvas of reality that God has given to us in His Word.
