What are The Four Acts of the Spirit we discover in Ephesians 5? These Acts are presented in two linked pairs of action by Paul. Two are "one-another actions" (19a and 21). Two are "toward-God actions" (19b and 20).
"Vertical submission" is NOT what Paul teaches in Ephesians 5:19 and following. He replaces that with "horizontal submission." Christ is our model. Sadly, most people have the over/under idea of vertical submission in mind as they read these verses.
Paul encourages Christians to teach and admonish one another (verse 5:19a). Then they are to submit to this teaching and correction they are receiving from one another (verse 21).
This is a horizontal RECIPROCAL SUBMISSION. This is how Spirit-filled believers build up one another in the body of Christ.
