2 John 1:2
For the truth's sake, which dwelleth in us, and shall be with us for ever.
For the truth's sake, which dwelleth in us,.... Not for her high birth, nobility, or riches; but either for Christ's sake, who is the truth, and who dwells in the hearts of believers by faith, and who is the same that dwells in one as in another; and on his account it is that saints love one another, because they belong to him, he is formed in them, and his image is stamped upon them; and every like loves its like: or for the Gospel's sake, which has a place, and dwells in every saint, and is the same for matter and substance in one as in another; and unity of mind and judgment produces unity of affection: or for the sake of the truth of grace, the inward principle of grace, which dwells in every regenerate person; a communication of the experience of which knits the saints one to another:
and shall be with us for ever; where Christ enters and takes up his abode, from thence he never finally and totally departs, though he may sometimes hide his face with respect to communion, or withdraw his gracious presence; and where the Gospel has once took place in the heart, and is become the ingrafted word, it can never be rooted out, or be removed; and where the truth of grace is, it will remain; it is an incorruptible seed, a well of living water, springing up into eternal life.
