3:22-24 When believers had confidence towards God, through the Spirit of adoption, and by faith in the great High Priest, they might ask what they would of their reconciled Father. They would receive it, if good for them. And as good-will to men was proclaimed from heaven, so good-will to men, particularly to the brethren, must be in the hearts of those who go to God and heaven. He who thus follows Christ, dwells in Him as his ark, refuge, and rest, and in the Father through him. This union between Christ and the souls of believers, is by the Spirit he has given them. A man may believe that God is gracious before he knows it; yet when faith has laid hold on the promises, it sets reason to work. This Spirit of God works a change; in all true Christians it changes from the power of Satan to the power of God. Consider, believer, how it changes thy heart. Dost not thou long for peace with God? Wouldst thou not forego all the world for it? No profit, pleasure, or preferment shall hinder thee from following Christ. This salvation is built upon Divine testimony, even the Spirit of God.

and he in him—Christ in the believer. Reciprocity. "Thus he returns to the great keynote of the Epistle, abide in Him, with which the former part concluded" (1Jo 2:28).
hereby—herein we (believers) know that he abideth in us, namely, from (the presence in us of) the Spirit "which He hath given us." Thus he prepares, by the mention of the true Spirit, for the transition to the false "spirit," 1Jo 4:1-6; after which he returns again to the subject of love.
