1. Deeds of Devotion to God and His Will

World Scripture

Whatever you do, do all to the glory of God.
1 Corinthians 10.31

Let all your deeds be done for the sake of Heaven.
Mishnah, Avot 2.17 (Judaism)

The most excellent action is love for God’s sake and hatred for God’s sake.
Hadith of Abu Dawud (Islam)

He is the Living One; there is no god but He: call upon Him, giving Him sincere devotion.
Qur’an 40.65

You shall love the Lord your God with all your heart, with all your soul, and with all your might. And these words which I command you this day shall be upon your heart; and you shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise. And you shall bind them as a sign upon your hand, and they shall be as frontlets between your eyes. And you shall write them upon the doorposts of your house and upon your gates.
Deuteronomy 6.5-9

Whatever I am offered in devotion with a pure heart—a leaf, a flower, fruit, or water—I partake of that love offering. Whatever you do, make it an offering to me—the food that you eat, the sacrifices that you make, the help you give, even your suffering. In this way you will be freed from the bondage of karma.
Bhagavad-Gita 9.26-27 (Hinduism)

Holy is the man of devotion; Through thoughts and words and deed And through his conscience he increases Righteousness; The Wise Lord as Good Mind gives the dominion. For this good reward I pray.
Avesta, Yasna 51.21 (Zoroastrianism)

Teachings of Sun Myung Moon

The spirit of loyalty, filial piety and integrity, which stands as straight as the pine or bamboo, will be the central thought and spirit of the Kingdom of God on earth that is to be established. We must be loyal to heaven because heaven is God’s country. We must offer eternal filial devotion to God because He is the Father of humankind.
(100:253, October 19, 1978)

You are doing things on behalf of God, so you must know God’s circumstances and what He is doing right now. In order to be God’s representatives, you should make sure that you represent God’s point of view, follow the path of His Will, and know where He would have you go.
(70:257, February 13, 1974)

What shall we do in order to receive God’s love? Since God has total love for us, we should also invest totally. The saying, “Sincerity moves Heaven,” like “Faith will move mountains,” is a proverb in Korea, but truly it is also the natural order of things. The proverb, “Act with utmost sincerity,” means act with all your efforts, inside and outside, heart and soul. The saying, “Practice everything with sincerity in your words and deeds,” means to completely unite your body and soul in a conscientious life. This means a life of dedication. We call it “utmost sincerity” or jeongseong. The Korean word jeong deals with the spirit, and song means the fulfillment of the Word. Thus jeongseong means fulfilling everything inwardly and outwardly and offering it.²⁶ If you do everything with jeongseong you can “move heaven.”
When Heaven moves, what happens? Since God has regard for such people, He makes His love dwell with them. Love wants to be with them. Love naturally dwells with people whose thoughts are for God and all His creatures. Therefore, when you offer jeongseong, you stand in a position to receive God’s love. As God loves all humankind, if you offer everything with jeongseong for the sake of God you will feel God’s love from the very first moment, and as a result you can love God.
Due to the Fall, we cannot truly love God. Therefore, by offering jeongseong for God, God’s love that has been searching for us can find us, and through that love we can come to know God and to love God.
(78:31-32, May 1, 1975)

Without a heart of utmost sincerity (jeongseong) and love, it is absolutely impossible to root out Satan’s lineage. How else can we completely pull out the root that was planted when Adam and Eve fell, that extends deep into God’s heart and torments God as He deals with the world’s sorrowful history? If we are to succeed in pulling out that root, we have to dig beneath it. That means we must go to a place of suffering more intense than the pain of God. If God is sleeping, we should be awake. We should willingly stand in a position hundreds of times more painful than what God’s heart experienced at the time of the Fall; only then can we pull out Satan’s root. Our heart of devotion should go that deep.
