Be quiet and take a step down from that deluded throne of self righteousness. Whether Jonathan wants to glorify the name of Jesus behind a jazz rhythm or a bagpipe, all the Glory goes to kingdom of God!! I question the validity of your faith if you lack what little amount of discernment it requires to see the spirit that moves through this mans music is not of the world. Before you respond read and meditate upon Romans 14:5-14. Regardless of what you believe to be 'More Holy' music, tame your tongue and use wisdom before you speak to your family in Christ.
'One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind. 6 The one who observes the day, observes it in honor of the Lord. The one who eats, eats in honor of the Lord, since he gives thanks to God, while the one who abstains, abstains in honor of the Lord and gives thanks to God. 7 For none of us lives to himself, and none of us dies to himself. 8 For if we live, we live to the Lord, and if we die, we die to the Lord. So then, whether we live or whether we die, we are the Lord's. 9 For to this end Christ died and lived again, that he might be Lord both of the dead and of the living.
10 Why do you pass judgment on your brother? Or you, why do you despise your brother? For we will all stand before the judgment seat of God; 11 for it is written,
“As I live, says the Lord, every knee shall bow to me,
and every tongue shall confess[b] to God.”
12 So then each of us will give an account of himself to God
13 Therefore let us not pass judgment on one another any longer, but rather decide never to put a stumbling block or hindrance in the way of a brother. 14 I know and am persuaded in the Lord Jesus that nothing is unclean in itself, but it is unclean for anyone who thinks it unclean.
