Do not by your eating destroy your brother for whom Christ died. Do not allow what you consider good to be spoken of as evil. For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, because anyone who serves Christ in this way is pleasing to God and approved by men. Let us therefore make every effort to do what leads to peace and to mutual edification. Do not destroy the work of God for the sake of food.
All food is clean, but it is wrong for a man to eat anything that causes someone else to stumble.
If our choice of music is a stumbling block to another Christian, then our responsibility is to put their best interests first and not to flaunt our freedom to listen to it. Everyone is different and if someone regards a particular style of music as inappropriate, then for them it is. Love is the standard by which we judge what is right and wrong when it comes to differences of opinion over things such as music. The kingdom of God is not a matter of what kind of music we are free to enjoy but of righteousness, peace and joy in the Holy Spirit. Make every effort to do what leads to peace and mutual edification when discussing such things as music.
