SHOWING HUMILITY AND REPENTANCE
One reason we fast is to demonstrate humility before the sovereign Creator of the universe. God responds when we diligently and wholeheartedly seek Him (2 Chronicles 7:14 If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land).
Sometimes this involves confession and repentance from sin. This was the case of the Ninevites when Jonah reluctantly told them God was going to bring judgment upon them (Jonah 3:5,10 So the people of Nineveh believed God, and proclaimed a fast, and put on sackcloth, from the greatest of them even to the least of them. 10 And God saw their works, that they turned from their evil way; and God repented of the evil, that he had said that he would do unto them; and he did it not), So they called a fast and repented of their sin. Fasting demonstrates humility by acknowledging our dependence on God.
In Psalm 35, David laments his enemies’ harsh treatment of him in contrast to how he cared for them when they were ill. He humbled his soul by fasting and praying for their recovery (Psalm 35:13 But as for me, when they were sick, my clothing was sackcloth: I humbled my soul with fasting; and my prayer returned into mine own bosom).
