“In describing the Christian’s love toward his brother, the Bible uses such expressions as “Love one another deeply, from the heart” (1 Peter 1:22) and “Be devoted to one another in brotherly love” (Romans 12:10). Other translations choose such words as fervently, fondly, and affectionately in the same passages to describe the love Christians ought to have for one another. Three different writers use the expression “brotherly love” or “love as brothers,” all indicating that Christian love is to be characterized by an affection that family members have—or ought to have—for one another (see Hebrews 13:1 and 1 Peter 3:8). All of these passages from the Bible indicate that our emotions are involved. We are to reach out and embrace our brother with a deep fervency of spirit, in our hearts if not in actuality. Obviously, such a fervency of spirit cannot substitute for loving actions, but surely it should accompany them. We dare not settle for less.”
