If you think in your heart of hearts that harps, timbrels and tambourines are a sin, then you must by all means go where they are not used in worship. For me, to praise the Lord on harps, timbrels, stringed instruments and tambourines ARE, as you know, specifically listed in the very Psalms which I am to praise the Lord with in my heart. . and I COULD dance before the Lord in some instances, no Michal (David's wife) could stand before God and despise me for it . . but I MUST not and will not do anything that causes my brother to stumble or try to convince him or her to do anything that he considers a sin in his heart. So, have joy in whatever you are convicted of in the Lord, for as you know, whatever you are convinced of as a sin, is TO YOU a sin. (In other words, I would not go to your church and attempt to bring a harp, timbrel or tambourine, or to dance before the Lord, as it would be an offence to the beliefs of your church (the church is PEOPLE, and not an earthly building). Let all things be done decently and in order.
I appreciate your thoughts on this, but this is not an issue that is a matter of personal choice.
