Hereby know we, etc. - See the note on 1 John 3:24.
Hereby know we that we dwell in him - Here is another, or an additional evidence of it.
Because he hath given us of his Spirit - He has imparted the influences of that Spirit to our souls, producing “love, joy, peace, long-suffering, gentleness, goodness, faith,” etc., Galatians 5:22-23. It was one of the promises which the Lord Jesus made to his disciples that he would send the Holy Spirit to be with them after he should be withdrawn from them, John 14:16-17, John 14:26; John 15:26; John 16:7, and one of the clearest evidences which we can have that we are the children of God, is derived from the influences of that Spirit on our hearts. See this sentiment illustrated in the notes at Romans 8:16.
This is the testimony that must go throughout the length and breadth of the world. It presents the law and the gospel, binding up the two in a perfect whole. (See Romans 5 and 1 John 3:9 to the close of the chapter.) These precious scriptures will be impressed upon every heart that is opened to receive them. “The entrance of Thy words giveth light; it giveth understanding unto the simple”—those who are contrite in heart. “As many as received Him, to them gave He power to become the sons of God, even to them that believe on His name.” These have not a mere nominal faith, a theory of truth, a legal religion, but they believe to a purpose, appropriating to themselves the richest gifts of God. They plead for the gift, that they may give to others. They can say, “Of His fullness have all we received, and grace for grace.” TM 94.1
“He that loveth not knoweth not God; for God is love. In this was manifested the love of God toward us, because that God sent His only-begotten Son into the world, that we might live through Him. Herein is love, not that we loved God, but that He loved us, and sent His Son to be the propitiation for our sins. Beloved, if God so loved us, we ought also to love one another. No man hath seen God at any time. If we love one another, God dwelleth in us, and His love is perfected in us. Hereby know we that we dwell in Him, and He in us, because He hath given us of His Spirit.” TM 94.2Read in context »
The apostle John realized that brotherly love was waning in the church, and he dwelt particularly upon this point. Up to the day of his death, he urged upon believers the constant exercise of love for one another.... UL 358.5Read in context »
