The Kingdom Come

As my family returned from church today, there were many questions. You see, the sermon was on homosexuality and how it is no worse a sin than any other sin. I mean, the Bible does say sin is sin right (Rom 3:23)? This confuses many people because then who are we to say anything about anyone's sins; specifically homosexuals if we are equally sinful? I mean, what about the Bible verse of removing the board out of your own eye before trying to help another person remove a speck (Mt 7:2-5)?
