The Bible says, "Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you," Ephesians 4:32. Being kind to others is showing Jesus to others. It's just one way we can let our lights shine for Him.
Love is patient and kind...1 Corinthians 13:4a.
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control; against such things there is no law. Galatians 5:22-23
God showed his loving kindness to us by giving up His Son to die on the cross for us. No act of kindness has ever been shown that is greater than that one act. But we can do little things to show kindness to others that can point them to Him. Our little actions, no matter how small, can be used to tell others about that one huge act that can save them.
How can you be kind today?
