Giving online is simple. First, select the amount, then under "fund" pick what category your tithe is going towards, lastly, choose what kind of payment such as: one-time, weekly, monthly, etc.
You can personally tithe at church on Wednesday nights at 6:30 pm and Sunday mornings at 10:00 am. Fill out a tithe envelope in the foyer if you want to keep track out how much you tithed for the year.
You can mail checks to PO Box 1707, Oroville WA, 98844
