Christians can sing a psalm. Psalm simply means a pious song, and it may or not not be one found in the bible.
Did God command Christians to play a 'carnal harp'?
A carnal harp does not teach or admonish as singing does.
Let us see.....
Harps used in the Psalms..
Praise the Lord with the HARP 33:2
upon the harp I will praise the 43:4
Harps used in 49:4, 57:8, 71:22, 81:2, 92:3, 98:5, 108:2, 147:7, 149:3, 150:3
Revelation USES of the HARP
Revelation 14:2 I heard the voice of harpers harping
Revelation 18:22 And the voice of harpers, and MUSICIANS
Revelation 5:8 having EVERY ONE OF THEM HARPS
Do you actually know how ignorant you appear? Why don't you go to God and tell HIM how harps and the use of HARPS are carnal in worship and remind HIM that he is contradicting his word by ALLOWING the use of HARPS in the INSPIRED SONGS of WORSHIP in the O.T. and that he is MISTAKEN for ALLOWING HARPS in HEAVEN and actually passing them out to the ones in CHAPTER 5 of REVELATION....
Do you actually swallow the crap that you put out? Are you seriously that blind and or deceived or just to full of pride to admit you miss the mark on many things......?
Serious dude, you should loose your COC doctrine and come on line with the truth.....! First and foremost actually trust Jesus and be born again of the spirit so as to be able to understand the truth.
