The chapter ends with clear instruction: “Stop regarding man…” (v. 22).  In order to make sense of this section, it is important to realize that the instruction in v. 22 is designed to move people out from under the terrible situation of being “rejected” by God (v. 6).  We are given more specifics concerning why God rejected His people (vv. 6b-11), what God will do to judge them (vv. 12-18), and how the rejected will respond to the “terror of the Lord” (vv. 19-21).  The way to avoid God’s fierce judgment is provided in v. 22–worship God, not man.  This is a good section to offset man’s arrogance with the humility of our Lord Jesus Christ (cf. Phil. 2).
