Paul is greeting the church in metro Ephesus, and therefore greeting you and me. It’s that part of the letter we typically fly through - but today it will show us something life-changing and even reveal Jesus more clearly. In fact, seeing how God greets you here in two short verses can affect all you say, think, or do.
Coram Deo simply means "face-to-face" with God. It's the posture we live where we are (1) in the presence of God, (2) under the authority of God, and (3) to the glory of God. Paul, in his letter to the greater church in metro Ephesus, helps us see not only the power of God's gospel to change us from the inside out, but also how that plays out in our lives as husbands, wives, employees, etc... Paul helps us see Coram Deo living as we are in Christ.
