1 John 5:1

I. The apostle having, in the conclusion of the last chapter, as was there observed, urged Christian love upon those two accounts, as suitable to Christian profession and as suitable to the divine command, here adds a third: Such love is suitable, and indeed demanded, by their eminent relation; our Christian brethren or fellow-believers are nearly related to God; they are his children: Whosoever believeth that Jesus is the Christ is born of God, Jo1 5:1. Here the Christian brother is, 1. Described by his faith; he that believeth that Jesus is the Christ - that he is Messiah the prince, that he is the Son of God by nature and office, that he is the chief of all the anointed world, chief of all the priests, prophets, or kings, who were ever anointed by God or for him, that he is perfectly prepared and furnished for the whole work of the eternal salvation - accordingly yields himself up to his care and direction; and then he is, 2. Dignified by his descent: He is born of God, Jo1 5:1.
