Why is kindness so against our natures that it takes the power of the Spirit of God to have it in our hearts? Kindness is listed in Galatians 5:22 & 23 as a fruit of the Spirit. Kindness is part of Yahweh’s nature.
It is His kindness that leads us to repentance (Romans 2:4). It was His kindness toward Nineveh that made Jonah most angry against Him: after having sent Jonah to prophesy to them, and dealing harshly with Jonah until he obeyed, Yahweh changed His mind and stirred the city with repentance, and spared them the destruction. Jonah was “angry enough to die.” Yahweh was compassionate toward the 120,000 people living in the city who “don’t know their right hand from their left.” (Jonah 4).
Concern yourself with observing your actions toward and responses to other people – whether you are being kind. It seems to be important to Yahweh.
