1 John 5:1

“Whosoever believeth that Jesus is the Christ, &c.] Or the Messiah that was prophesied of old, was long promised to the Jews, and whom they expected; there was a person spoken of in the writings of the Old Testament under this character, (<190202>Psalm 2:2 <270925>Daniel 9:25,26); and the Jews looked for him; and Jesus of Nazareth is he, as appears by all the characteristics of the Messiah in prophecy being found upon him: this the Jews deny, but is the grand article of faith embraced by the apostles and followers of Jesus, and is of very great importance; he that denies it is a liar, and he that does not believe it shall die in his sins: the word signifies “anointed”, and includes all the…”

“WHO ARE THE BRETHREN ESPECIALLY TO BE LOVED (Jo1 4:21); OBEDIENCE, THE TEST OF LOVE, EASY THROUGH FAITH, WHICH OVERCOMES THE WORLD. LAST PORTION OF THE EPISTLE. THE SPIRIT'S WITNESS TO THE BELIEVER'S SPIRITUAL LIFE. TRUTHS REPEATED AT THE CLOSE: FAREWELL WARNING. (1Jo. 5:1-21) Reason why our "brother" (Jo1 4:21) is entitled to such love, namely, because he is "born (begotten) of God": so that if we want to show our love to God, we must show it to God's visible representative. Whosoever--Greek, "Everyone that." He could not be our "Jesus" (God-Saviour) unless He were "the Christ"; for He could not reveal the way of salvation, except He were a prophet: He could not work out that salvation,…”

“Whosoever believeth that Jesus is the Christ - Is the Messiah; the anointed of God. On the meaning of the word Christ, see the notes at Matthew 1:1. Of course, it is meant here that the proposition, that “Jesus is the Christ,” should be believed or received in the true and proper sense, in order to furnish evidence that anyone is born of God. Compare the notes at 1 John 4:3. It cannot be supposed that a mere intellectual acknowledgment of the proposition that Jesus is the Messiah is all that is meant, for that is not the proper meaning of the word believe in the Scriptures. That word, in its just sense, implies that the truth which is believed should make its fair and legitimate impression…”

“The scope and sum of this whole paragraph appears from the conclusion of it, Jo1 5:13, "These things have I written to you who believe, that ye may know that ye who believe have eternal life." So faith is the first and last point with St. John also. Every one who loveth - God that begat loveth him also that is begotten of him - Hath a natural affection to all his brethren. 1 John 5:2”

“5:1-5 Those who believe that Jesus is the Christ and the Son of God have been born spiritually as children of God (see John 20:31). Such people are empowered by the Spirit of God to love him and others, and by their faith to obey God and overcome the evil temptations of the world. Through faith, they can love God and live in obedience to him.”
