"We experience God's grace because God is gracious. In Exodus 34:6, when God is showing himself to Moses, we read "The Lord, the Lord, the compassionate and gracious God, slow to anger, abounding in love and faithfulness." Gracious is used here as an adjective describing God. It is one of his attributes.
Gracious, the Hebrew word channun, in its verb form, means to be considerate, to show favor. That God is gracious would mean that he is favorably inclined toward us. That he wants to show favor to us. To do what is best for us.
God is gracious. Graciousness is not something that he puts on and takes off depending on the situation. He is always gracious. He does not decide to show us grace. Rather it is just who he is. Because he is gracious he demonstrates grace in everything he does."
