1-john 5:3

For this is the love of God - This the love of God necessarily produces. It is vain to pretend love to God while we live in opposition to his will.

His commandments - To love him with all our heart, and our neighbor as ourselves, are not grievous - are not burdensome; for no man is burdened with the duties which his own love imposes. The old proverb explains the meaning of the apostle's words, Love feels no loads. Love to God brings strength from God; through his love and his strength, all his commandments are not only easy and light, but pleasant and delightful.

On the love of God, as being the foundation of all religious worship, there is a good saying in Sohar Exod., fol. 23, Colossians 91:"Rabbi Jesa said, how necessary is it that a man should love the holy blessed God! For he can bring no other worship to God than love; and whoever loves him, and worships him from a principle of love, him the holy blessed God calls his beloved."

For this is the love of God, that we keep his commandments - This constitutes true love; this furnishes the evidence of it.

And his commandments are not grievous - Greek, "heavy" - βαρεῖαι bareiai; that is, difficult to be borne as a burden. See Matthew 11:30. The meaning is, that his laws are not unreasonable; the duties which he requires are not beyond our ability; his government is not oppressive. It is easy to obey God when the heart is right; and those who endeavor in sincerity to keep his commandments do not complain that they are hard. All complaints of this kind come from those who are not disposed to keep his commandments. Indeed, they object that his laws are unreasonable; that they impose improper restraints; that they are not easily complied with; and that the divine government is one of severity and injustice. But no such complaints come from true Christians. They find his service easier than the service of sin, and the laws of God more mild and easy to be complied with than were those of fashion and honor, which they once endeavored to obey. The service of God is freedom; the service of the world is bondage. No man ever yet heard a true Christian say that the laws of God, requiring him to lead a holy life, were stern and "grievous." But who has not felt this in regard to the inexorable laws of sin? What votary of the world would not say this if he spoke his real sentiments? Compare the notes at John 8:32.

5:3 For this is the love of God - The only sure proof of it.That we keep his commandments: and his commandments are not grievous - To any that are born of God.
