You can send the message below or personalize your own:

As a person of faith and your constituent, I want to let you know I am praying for you as you represent me. You are making decisions and craft legislation that affects our nation--seek truth, protect all people of faith, and honor the Constitution.  If you need wisdom, know that God promises it to those who ask, as it says in James 1:5. I hope you find that to be an encouragement.
