Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver. And God is able to bless you abundantly, so that in all things at all times, having all that you need, you will abound in every good work. 2 Corinthians:7-8
You have several options for your weekly offerings or one-time gift:
"All contributions directed towards an approved program or project will be used as restricted with the understanding that when the need for such a program or project has been met, or cannot be completed for any reason, the remaining restricted contributions will be used where most needed."
