Psalm 8:2 comes to mind...
That if we want to see revival, we need to rally the troops who, by just their worshipping alone, can silence the enemy......a constant thought behind all I do!
I'm a children's minister, so have some bias here. But I'm also a musical worship leader of some 30 years plus.
Children's ministry always attracts FAR more determined, and serious, spiritual opposition than any opposition I've ever encountered leading musical worship.
