What does the Bible say about Christian kindness?

In Colossians 3:12-15, the Apostle Paul instructs believers to put on kindness as a vital part of their Christian walk. As the elect of God, called to reflect His character, Christians are encouraged to embrace kindness alongside other virtues such as humility and meekness. This direct command emphasizes that kindness should not merely be an external act but rather stem from a heart transformed by God’s grace. Our understanding of kindness is enriched when we recognize it as a by-product of God's mercy toward us, leading us to extend that same mercy to others.
