7 Beloved, I am writing you no new commandment, but an old commandment that you had from the beginning. The old commandment is the word that you have heard. 8 At the same time, it is a new commandment that I am writing to you, which is true in him and in you, because[1] the darkness is passing away and the true light is already shining. 9 Whoever says he is in the light and hates his brother is still in darkness. 10 Whoever loves his brother abides in the light, and in him[2] there is no cause for stumbling. 11 But whoever hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.
12 I am writing to you, little children, because your sins are forgiven for his name's sake. 13 I am writing to you, fathers, because you know him who is from the beginning. I am writing to you, young men, because you have overcome the evil one. I write to you, children, because you know the Father. 14 I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one. 15 Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. 16 For all that is in the world-- the desires of the flesh and the desires of the eyes and pride in possessions--is not from the Father but is from the world. 17 And the world is passing away along with its desires, but whoever does the will of God abides forever.

Commentary on 1 John 2:3-11
(Read 1 John 2:3-11)
What knowledge of Christ can that be, which sees not that he is most worthy of our entire obedience? And a disobedient life shows there is neither religion nor honesty in the professor. The love of God is perfected in him that keeps his commandments. God's grace in him attains its true mark, and produces its sovereign effect as far as may be in this world, and this is man's regeneration; though never absolutely perfect here. Yet this observing Christ's commands, has holiness and excellency which, if universal, would make the earth resemble heaven itself. The command to love one another had been in force from the beginning of the world; but it might be called a new command as given to Christians. It was new in them, as their situation was new in respect of its motives, rules, and obligations. And those who walk in hatred and enmity to believers, remain in a dark state. Christian love teaches us to value our brother's soul, and to dread every thing hurtful to his purity and peace. Where spiritual darkness dwells, in mind, the judgment, and the conscience will be darkened, and will mistake the way to heavenly life. These things demand serious self-examination; and earnest prayer, that God would show us what we are, and whither we are going.
Commentary on 1 John 2:12-14
(Read 1 John 2:12-14)
As Christians have their peculiar states, so they have peculiar duties; but there are precepts and obedience common to all, particularly mutual love, and contempt of the world. The youngest sincere disciple is pardoned: the communion of saints is attended with the forgiveness of sins. Those of the longest standing in Christ's school need further advice and instruction. Even fathers must be written unto, and preached unto; none are too old to learn. But especially young men in Christ Jesus, though they are arrived at strength of spirit and sound sense, and have successfully resisted first trials and temptations, breaking off bad habits and connexions, and entered in at the strait gate of true conversion. The different descriptions of Christians are again addressed. Children in Christ know that God is their Father; it is wisdom. Those advanced believers, who know Him that was from the beginning, before this world was made, may well be led thereby to give up this world. It will be the glory of young persons to be strong in Christ, and his grace. By the word of God they overcome the wicked one.
Commentary on 1 John 2:15-17
(Read 1 John 2:15-17)
The things of the world may be desired and possessed for the uses and purposes which God intended, and they are to be used by his grace, and to his glory; but believers must not seek or value them for those purposes to which sin abuses them. The world draws the heart from God; and the more the love of the world prevails, the more the love of God decays. The things of the world are classed according to the three ruling inclinations of depraved nature. 1. The lust of the flesh, of the body: wrong desires of the heart, the appetite of indulging all things that excite and inflame sensual pleasures. 2. The lust of the eyes: the eyes are delighted with riches and rich possessions; this is the lust of covetousness. 3. The pride of life: a vain man craves the grandeur and pomp of a vain-glorious life; this includes thirst after honour and applause. The things of the world quickly fade and die away; desire itself will ere long fail and cease, but holy affection is not like the lust that passes away. The love of God shall never fail. Many vain efforts have been made to evade the force of this passage by limitations, distinctions, or exceptions. Many have tried to show how far we may be carnally-minded, and love the world; but the plain meaning of these verses cannot easily be mistaken. Unless this victory over the world is begun in the heart, a man has no root in himself, but will fall away, or at most remain an unfruitful professor. Yet these vanities are so alluring to the corruption in our hearts, that without constant watching and prayer, we cannot escape the world, or obtain victory over the god and prince of it.
