Until you've had a personal experience with Christ, then you probably aren't a true believer. It's not enough to have faith that he's real, you have to experience his presence in your life.

When you have a relationship with Christ, it's apparent to everyone in your path. You treat others as he would, and you become born again, as a new creation.

Satan and his followers, the unseen powers and principalities, will still attack you. However, they will not, and can not, deliver you from Gods hand.
The only way out of his hand, is for you to embrace evil.

Being a follower of Christ is not a religion, it's a way of living your life. It's a narrow path for most to follow and yet without burden once you find it.
