1 Peter 1:22-25 - Love Each Other

²² You that have purified your souls by the holy spirit, in obeying the gospel, which obliges you to an undisguised benevolence, let your hearts be mutually affected with the most disinterested ardour; ²³ since your regeneration is not owing to any corruptible principles, but to the unchangeable word of the immortal God. ²⁴ for human nature is like grass, and all their glory like the flower of the herb, the herb withers, the flower droops, ²⁵ but the word of the Lord remains for ever: and that is the gospel, which has been preached to you.
