Isaiah 55:10-11 – As the rain and snow come down from heaven, and do not return to it without watering the earth . . . so is my word that goes out from my mouth: It will not return to me empty, but will accomplish what I desire.
Isaiah 30:18 – Therefore the Lord waits to be gracious to you, and therefore He exalts Himself to show mercy to you. For the Lord is a God of justice; blessed are all those who wait for Him.
