Though every man be a liar, yet God is true.
I can not count how many times I have heard someone say that they would go to church but for the Church, or would be a Christian but for Christians. While that sentiment may be a legitimate indictment on the state of the Church and the faithlessness of Christians (or not), what should we really expect? We have all sinned and fallen short. There is no one righteous, not even one!
That people are people, however, has no bearing whatsoever on God.
