In the same way going to church, bible study, and doing volunteer work throughout the week doesn't make you a "Christian" either. So what does? The all famous phrase "Christianity isn't a religion its a __________." I'll let you think about that one for a second... Alright, if you answered anything other then "relationship" please leave a comment with what you put, I'll get with you later. (In fact, I wish people would leave comments on my posts period.) You need to have Jesus in your heart.
Any good relationship is a two way street. You wouldn't spend time with your spouse, children, siblings, or good friends on the weekend then forget they exist on Monday morning, would you? Why not? The same is true for God, He is our Heavenly Father and we should remember Him in all our actions throughout the week; keeping Him in our hearts. As we do this our relationship with the Creator will grow deeper and fonder.
So where do you keep Him the most? In a box? Or in your heart?
