"Shut in With God While John was contemplating the scenes of Horeb, the Spirit of Him who sanctified the seventh day came upon him. He contemplated the sin of Adam in transgressing the divine law, and the fearful result of that transgression. The infinite love of God, in giving His Son to redeem a lost race, seemed too great for language to express. As he presents it in his epistle he calls upon the church and the world to behold it. “Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not” ( 1 John 3:1 ). It was a mystery to John that God could give His Son to die for rebellious man. And he was lost in amazement that the plan of salvation, devised at such a cost to Heaven, should be refused by those for whom the infinite sacrifice had been made. SL 75"
"Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not."
EGW directly quotes 1 John 3:1 and elaborates on its meaning within the context of God's love and the plan of salvation.
"John was shut in with God. As he learned more of the divine character through the works of creation, his reverence for God increased. He often asked himself, Why do not men, who are wholly dependent upon God, seek to be at peace with Him by willing obedience? He is infinite in wisdom, and there is no limit to His power. He controls the heavens with their numberless worlds. He preserves in perfect harmony the grandeur and beauty of the things which He has created. Sin is the transgression of God's law, and the penalty of sin is death. There would have been no discord in heaven or in the earth if sin had never entered. Disobedience to God's law has brought all the misery that has existed among His creatures. Why will not men be reconciled to God? SL 75.2"
"Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law."
The EGW passage directly states, "Sin is the transgression of God's law," which is a direct paraphrase of 1 John 3:4: "Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law."
"Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin."
The EGW passage mentions that sin is the transgression of God's law. Romans 3:20 states that the law gives knowledge of sin. While not a direct quote, the principle is the same: the law defines sin.
