Love is kind, so God is kind. The word in the original language is a unique blend of gentleness, and goodness.
In English, kind has a connotation of gentle. In other words, a kind person does not treat others harshly. A kind person has soft words, and actions. Even words or correction and rebuke are soft. They get the necessary point across, but without additional pain.
But, in the original language, the term has a component of being using, or being beneficial. There is a component of service. So, not only does a kind person not seek to cause pain and injury, but he uses words and deeds to benefit or enhance.
God could destroy us. God could inflict tremendous pain and punishment. As rebels against him, we deserve all of it. But he seeks the opposite. He seeks to build a family. He heals. He reconciles. He finds a way past sin and rebellion toward intimate relationship.
It is written in Scripture, that we change our direction in life, not because God threatens judgment, or punishes evil. We change our direction because God is kind to us. He acted to bring us back to him in Christ's death on the cross. He speaks to us to lead us to him, to restore our joy, and our original design. He provides for us physically, emotionally, and spiritually.
