 So some people say, I believe in Jesus, therefore I'm saved. Well, do you believe in the way the Bible tells you to believe? Jesus said, for God so loved the world, he gave his only begotten son, and whosoever believes in him should not perish, but have everlasting life. By implication, believing means to take hold of one thing and let go of another. Or to put it another way, it's to believe in and repent of.
