I choose not to believe the Bible,
but if I did, I wouldn't try to twist the verses to fit my agenda, or the agenda of my pastor/church.
You quoted "Malachi 3:8 Will a man rob God? Yet ye have robbed me. But ye say, Wherein have we robbed thee? In tithes and offerings."
Back up a little there, Who is "God" talking to there?
Well, to find that out, you'd have to back all the way up to Malachi 2:1, which says, "And now, O ye priests, this commandment is for you."
Wow, the priest were robbing "God", just like they are doing today.
I'm willing to debate tithing with you, What say you?
