When I extend mercy to others, God extends mercy to me.

Isaiah 58:9-11

Then you will call, and the LORD will answer. You will cry for help, and he will say, ‘Here I am.’ If you take away from among you the yoke, finger pointing, and speaking wickedly; and if you pour out your soul to the hungry, and satisfy the afflicted soul, then your light will rise in darkness, and your obscurity will be as the noonday; and the LORD will guide you continually, satisfy your soul in dry places, and make your bones strong. You will be like a watered garden, and like a spring of water whose waters don’t fail.
