Isn't it odd that Paul would tell us that love is kind? Most of us would say, "Of course, love is kind. Why would you have to state something like that?" It must mean that the love Paul speaks of is more than being kind to those who are kind to you or else he would never have had to make such a statement.
Let's suppose you are driving down the road when someone cuts you off. They do so while giving the single-fingered salute. Should you be expected to be kind to that person? You will if you understand that being a Christian means that you will love people.
Love transcends the actions of others. It is a clear decision to love that person regardless of their actions. It means that you love when you are not treated kindly. It means you respond with kindness.
Let's admit it. This type of love is impossible for those who try to do so under their own power. This must be a divine love. This is the type of love God has for us. This is the type of love God wants to give us for others. We must live our lives in the power of God's love. Our connection with Him allows us to love. Kindness to those who lack kindness is the evidence of this love.
So, today I will be kind because I love in God's power of love.
1 Corinthians 13:4 (NASB)
Love is kind.
