526 With the Truth There Is Strength
1 You must understand the significance of your giving up your families and expending yourselves for God, as well as why you want to do this. If it is to pursue truth, to pursue life, and to fulfill your duties and repay God’s love, then that is completely righteous—a positive thing—and it is Heaven’s law and earth’s principle. In that case, you will never have regrets, and you will not become negative. When people have truth, they have strength. When they have truth, they are filled with inexhaustible energy. When they have truth, they have will. Without truth, they are like the limp dregs of tofu. With truth, they are firm and emboldened, and they do not feel their suffering as suffering, no matter how much they endure.
2 If people have a genuine understanding of God’s disposition, and can give heartfelt praise to His holiness and righteousness, then it means they truly know Him and possess the truth; only then do they live in the light. Only once a person’s view of the world and of life changes does one undergo a fundamental transformation. When one has a life goal and comports oneself according to the truth, when one submits absolutely to God and lives by His words, when one feels peaceful and illuminated to the depths of one’s soul, when one’s heart is free of darkness, and when one can live entirely free and unrestrained in God’s presence, only then does one lead a genuine human life, and only then has one become a person who possesses the truth. In addition, all the truths in your possession have come from God’s words and from God Himself. The Ruler of the entire universe and all things—God Most High—approves of you as a real person. This is what it means to be in possession of the truth.
