3:1 That we should be called - That is, should be, the children of God. Therefore the world knoweth us not - They know not what to make of us. We are a mystery to them.

3:2 It doth not yet appear - Even to ourselves. What we shall be - It is something ineffable, which will raise the children of God to be, in a manner, as God himself. But we know, in general, that when he, the Son of God, shall appear, we shall be like him - The glory of God penetrating our inmost substance. For we shall see him as he is - Manifestly, without a veil. And that sight will transform us into the same likeness.

3:3 And every one that hath this hope in him - In God.

3:4 Whosoever committeth sin - Thereby transgresseth the holy, just, and good law of God, and so sets his authority at nought; for this is implied in the very nature of sin.

3:5 And ye know that he - Christ. Was manifested - That he came into the world for this very purpose. To take away our sins - To destroy them all, root and branch, and leave none remaining. And in him is no sin - So that he could not suffer on his own account, but to make us as himself.

7:29 But this I say, brethren - With great confidence. The time of our abode here is short. It plainly follows, that even they who have wives be as serious, zealous, active, dead to the world, as devoted to God, as holy in all manner of conversation, as if they had none - By so easy a transition does the apostle slide from every thing else to the one thing needful; and, forgetting whatever is temporal, is swallowed up in eternity.

7:30  And they that weep, as if they wept not - "Thoughsorrowful, yet always rejoicing." They that rejoice, as if they rejoiced not - Tempering their joy with godly fear. They that buy, as if they possessed not - Knowing themselves to be only stewards, not proprietors.

7:31 And they that use this world, as not abusing it - Not seeking happiness in it, but in God: using every thing therein only in such a manner and degree as most tends to the knowledge and love of God. For the whole scheme and fashion of this world - This marrying, weeping, rejoicing, and all the rest, not only will pass, but now passeth away, is this moment flying off like a shadow.

1:15 The time is fulfilled - The time of my kingdom, foretold by Daniel, expected by you, is fully come.

1:16  Mat 4:18; Luk 5:1.

1:18 Straightway leaving their nets, they followed him - From this time they forsook their employ, and constantly attended him.Happy they who follow Christ at the first call!
