The love that is mentioned here is unconditional love. This type of love is not natural for sinful human beings. Unconditional love is given freely, regardless of how lovable or unlovable the recipients are. This is how God loves us and He gives us His love to share with one another. When God’s people love each other with unconditional love, then each of us is encouraged and strengthened and our lives can truly reveal God’s grace and mercy to unbelievers.
