“and if my people who are called by my name become humble and pray, and look for me, and turn away from their evil ways, then I will hear them from heaven. I will forgive their sin and heal their land.
You must serve me with a pure and honest heart, just as your father David did. You must obey my laws and do everything that I commanded you. If you obey all I have commanded, and if you obey my laws and rules, then I will make you a strong king and your kingdom will be great. That is the agreement I made with David your father when I told him that Israel would always be ruled by one of his descendants.”
2 Chronicles 7:14, 17-18 ERV
