The scripture says: “It is kindness that I want, not animal sacrifices.” If you really knew what this means, you would not condemn people who are not guilty.
Matthew 12, 7

Kindness, that always sounds like warmth, or even like “hot heart” to me. If anyone sees a man, then he has a cold or warm heart for him. When His heart is cold, then he sees the errors and offenses. Is it warm, he sees chances and the good, strong sides. The Pharisees were not interested in people, they only cared whether anyone followed the rules.
When we listen to ourself what we say or even think about others, then we often realize how we get upset about outward things and possible errors. But this is not how God wants us to have! For He doesn’t deal with us this way, but sees us with eyes of love. He simply forgets our failures and constantly gives us a new start. He sees so many good sides of us and sees our possibilities! Yes, He is good and looks at us with a warm, actually even hot heart. Therefore, we want to see our fellow human beings with the eyes of Jesus and so think and talk about them as Jesus wants it.
What God requires of us, namely kindness, He is itself. He is the mercy in person. Just read the Gospels about the life of Jesus, there you will only find merciful deeds, thoughts and words. Just as He is with you. He is merciful to you. He is gracious to you. He loves you without fuss and quibble. He forgets your failure. He longs for you. Yeah, He is love and kindness in person.
If God is for us, who can be against us? Who can accuse God’s chosen people? It is God who justifies. Who can condemn? Not Christ Jesus, who died, or rather, who was raised to life and is at the right side of God, pleading with him for us! Who, then, can separate us from the love of Christ? Neither death nor life, neither angels nor other heavenly rulers or principalities, neither the present nor the future, neither the world above nor the world below – there is nothing in all creation that will ever be able to separate us from the love of God which is ours through Christ Jesus our Lord. (Rom. 8)

Thank You, Jesus, You are so full of kindness for me! Yes, I want to take Your mercy, it shall rule over me. I will bring You my concerns and needs, for You have only good thoughts about me. You are a wonderful Lord, my Savior and Redeemer!
