To be able to use worship as a weapon you have to be taking the time to charge your worship batteries. That is, take the time to listen to a few worship songs daily. That way when you encounter a tough situation, it's simple and natural for your mind to produce a song to worship the Lord. I grew up in church, so I know a lot of worship songs. However if I'm not taking the time to listen to a few daily, my batteries start dying. Worship songs are harder to come up with and instead I just say "Oh, forget it! I'm too mad to sing anyways"! It has to come to mind quickly or it's just not as effective.
Church is obviously a great place to recharge. However it's not always an option and even if it is, once a week isn't enough. So here are my 3 favorite places to worship.
1. In the car.
2. In the shower.
3. In the kitchen.
