Is there a Bible verse that relates to proclaiming faith?

(1 Timothy 1:5-7) "Really the objective of this mandate is love out of a clean heart and out of a good conscience and out of faith without hypocrisy. By deviating from these things certain ones have been turned aside into idle talk, wanting to be teachers of law, but not perceiving either the things they are saying or the things about which they are making strong ertions."
