Kindness is not some lofty ideal to work toward; rather we can practice it throughout the day, not just with the big things but with the little things. We all know that we should be kind. We were taught that as kids, sometimes as a correction to some not-so-kind behavior. As adults, however, our kindness is more proactive, more positive, often acknowledging the kindness of others.
Scripture is replete with the word: kind as a verb, kindness as a noun. Take your pick. However we read it, we know the implication, BE Kind.
Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you. Ephesians 4:32
Love is patient and kind.
1 Corinthians 13: 4
But love your enemies, and do good, and lend, expecting nothing in return, and your reward will be great, and you will be sons of the Most High, for he is kind to the ungrateful and the evil.
Luke 6:35
