PayPal "Subscription" 
The easiest way to donate on a month to month basis is to set up a "subscription" which will automatically charge whatever account elect to use once every month. Essentially you can set it and forget it.
You can, of course, cancel any time you choose to through PayPal.
All donations go to Bridge Church's Bridge to Missions program and are tax deductible. Be sure to fill out your address so the church can get you your tax documents at the end of every year.
Note: PayPal charges a fee of 2.9% + $0.30 USD per donation. Example: You donate $100, we get $96.80. For this reason we recommend that large donations be made directly to Bridge Church as explained here.
