In order to not lose the grace of God, strive more to acquire the remembrance of God. One must fulfill the word of God, i.e., the commandments, as the Lord Himself said: “He that hath My commandments, and keepth them, he it is that loveth Me” (John 14:21). In such a way there is achieved sincere service to God, with all one’s heart.
