They Should Have Honored Him

 “…They did not honor Him.” (Romans 1:21)

Man’s chief end is to honor and glorify God. (Leviticus 10:3; 1Chronicals 16:24-29; Psalms 148; Romans 15:5-6)

Scriptures demands it. (Psalms 29:1-2; 1Colossians 10:31; Revelation 4:11)

To honor Him is to glorify Him, to acknowledge His attributes and to praise Him for His perfections. (Deuteronomy 32:4)
Recognize God’s glory and honor him for it.  Failing to give God glory is man’s greatest affront to Him. (Acts 12:22-23)
