How do you sign 'faithful' in sign American sign lauguage?

Because there is no real sign for "faithful", you must explain the meaning of being faithful. For example, if you are a faithful customer to a certain store, you sign "GO-THERE-OFTEN" with the 1-CL and B-CL hand shapes. When I'm interpreting or just signing about God, I explain that I can depend on Him, His love never fails me, I never doubt His promises because they never fail me. He is always there, proven Himself again and again. I explain HOW He's been faithful without even using the sign "FAITH", unless I say, I have faith in God because He is........explaining WHY and HOW my God is faithful.
