From North Point’s website (giving FAQs):
Q: Do you have envelopes available for me to mail in my tithe?
A: Yes! If you would like for us to mail you a supply of envelopes for your tithe contributions, please send your name, address, and church name to envelopes@northpoint.org. A supply of envelopes is also available at the Information Center at each campus. If you typically place your tithe check in an offering bucket during worship services, you do not need to use an envelope.
Thank you. I knew it.
Tithing is strictly an Old Testament law. It is not carried over in the New Testament. Christians are encourage to give out of love (not Law), yet it never seems to fail that pastors like Stanly here want to glom onto the Old Law when it comes to money, money, money.
