Sincerity is indispensable if we are to achieve greater union with God.
If you have an ugly "toad" inside you, my son, let it out! As I have always advised you, the first thing you must mention is what you wouldn't like anybody to know. Once the "toad" has been let out in Confession -- how well one feels. (The Forge, 193)
Forward, no matter what happens! Cling tightly to Our Lord’s hand and remember that God does not lose battles. If you should stray from him for any reason, react with the humility that will lead you to begin again and again; to play the role of the prodigal son every day, and even repeatedly during the twenty-four hours of the same day; to correct your contrite heart in Confession, which is a real miracle of God’s Love. In this wonderful Sacrament Our Lord cleanses your soul and fills you with joy and strength to prevent you from giving up the fight, and to help you keep returning to God unwearied, when everything seems black. In addition, the Mother of God, who is also our Mother, watches over you with motherly care, guiding your every step. (Friends of God, 214, 5)
