Never Full
I have a relative which was raised as a Christian. Now, she is 83 and never has left the Christian faith: but I have often wondered if she ever met Christ. She can talk about church, doctrines and forms; but Christ and his love has never come off of her lips.
I have compassion for my Aunt. She is a good woman and has a good heart; but a Christian life without Christ is pretty unsatisfying. I too, spent years being a "good Christian" but never really knowing Christ. My life was driving by "being good" instead of knowing Christ.
To me, that kind of Christianity is like believing you have eaten when you only saw the pictures of food. Starving but deceived: unsatisfied, and never full.
