Have you noticed how lax our christianity has gotten? Sin is no longer sin in our churches, schools, and even relationships. I guess it's okay now to shack up with your boyfriend during the week and then go to church on the weekends and sing about God. Or you know, we cant judge gays because we need to love them instead. Even affairs are seen as okay in churches because of 'following your heart' or 'renewing high school romances'.
These things are open abominations to Christ. He has said over and over in His word how much he hates these things! Not only do these things destroy the Christian witness, but they also destroy the person doing them. God knows us. He knows our nature, and made rules in the Bible to protect us from destroying ourselves.
But do what you want. After all we can't be caught judging . . . It's cool to be tolerant, right?
