Music can split a church. And music make a friend. It can lead you into the light, or toward darkness. Listen wisely, and listen well.
You've heard it said - "You are what you eat". You also are what you do.
Many who say they are followers of Christ still find themselves anxious, having a troubled heart, because they are actually afraid to trust themselves to God. They do not make a complete and full surrender to Him - for they are afraid what the consequences of full surrender will be. Unless they do make this surrender though... they will not find peace.
Just because we've always done it this way, does not mean it has been the right way. The opposite is true too - just because this is a new idea, does not make it the right idea either.
If error is compounded over time - it does not gradually become right. It's just really entrenched error. And heard to escape.
It's hard for some of Jesus' would be followers. But if Jesus can call you... He can call those around you. "Settle" for introducing Jesus to people, and leave the conviction up to Him, and His Spirit.
Having an open mind leads to growth. If you are not going to stay the same, you will have to keep learning, otherwise you grow, but stay the same - and that is just a description for bloated.
