Are Christians 'nice' people?

If Christianity is true, then why are not all Christians obviously ‘nicer’ than non-Christians? The Pharisees still ask, as they always have, “Why eateth your Master with publicans and sinners?” (Matthew 9:11). To which the Lord promptly answers, “They that be whole need not a physician, but they that are sick” (Matthew 9:12). The difference between the non-Christian and Christian is this: the Christian has the Christ-life in them, the non-Christian does not. A Christian is not a person who never goes wrong. Rather, it is a person who because of the Christ-life inside them, is able to repent and pick themself up after each stumble. That is why the Christian is in a different position from a self-righteous prig who tries to be ‘nice’ on their own steam. The world hopes that by being ‘nice’ they can somehow please God, if they believe in Him, or win the accolades of men, if they do not. The Christian however thinks that any niceness they exhibit comes from the Christ-life inside them. The world must realize that God is not impressed by any humanistic efforts to be a ‘nice’ person. He will make you good however, through the Christ-life working in you, because He loves you. One writer said, “Do God or do good”. I’m afraid the two are not mutually exclusive. This is why it is written, “But we are all as an unclean thing, and all our righteousness are as filthy rags; and we all do fade as a leaf; and our iniquities, like the wind, have taken us away (Isaiah 64:6). What we call ‘nice’ is still ‘filthy rags’ in His sight. Our finite minds cannot possibly conceive how holy, pure and perfect God is. Christ therefore calls the world to repentance, not to be ‘nice people’ (Matthew 4:17). Being ‘nice’, as noble a virtue as it may seem, is secondary. Of primary importance is this, “Ye must be born again” (John 3:7). After that, and not a moment sooner, everything else falls into place.
