Keep your word. If you say that you will do something, be faithful to do it. Be on time for rehearsals, times of instruction, prayer, etc. Be a faithful and responsible member of the local fellowship. Speak edifying words to and of one another.
Love covers a multitude of sins.
Have the attitude of Jesus. Appreciate the gift of God in one another. If you have a problem or disagreement with someone, go to that person and in love, talk it over and pray it through until peace reigns. You are called to allow the life of God flow through you daily. Allow the Father to teach you how to give thanks in everything.
