Peter commands believers to love one another fervently and from the heart. This kind of love is not without sacrifice, but this investment of love is guaranteed to result in eternal benefit. Because our new life has its source in God's word, and because God's word endures forever, we can have confidence that the relationships we build with other believers are also eternal. We will forever share in the benefits of the sacrificial love we share on this side of eternity. An exposition of 1 Peter 1:23-25.
