Now My eyes will be open and My ears attentive to the prayer offered in this place.
-- 2 Chronicles 7:15
This was God saying his eyes and ears were attentive to the prayers offered in the temple of the Lord. Now his eyes and ears are attentive to prayers offered in his new temple. That temple is in our heart, each child of God is the temple of the Lord. We need to pray because we know God is listening and attentive. We sometimes pray and God doesn’t seem to answer, but you know it is not because he doesn’t hear, it is because he is saying you need to wait, or the answer is no. You have to trust him that he knows best.
and My people who are called by My name humble themselves, and pray and seek My face, and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land.
-- 2 Chronicles 7:14
This is a promise for the people who fail. That is most of the people, because we all fail and we get to enjoy the advantages of the promise. God knows everything and so he knows what our prayer would be, so what does it mean to hear from heaven? I think it means that God will get actively involved in fixing the issues that come from our sin, because we asked. We can’t fix them, we mostly make them worse, but God can fix us for now and fix us for eternity.
If I shut up the heavens so that there is no rain, or if I command the locust to devour the land, or if I send a plague among My people,
-- 2 Chronicles 7:13
God has the right to punish his people, or any nation for their sins. The nice thing for his people and for us, is he gave us numerous warning to keep us on track. Jonah had the chance to give a warning to Nineveh, but it is rare for God to do it for a heathen nation. Not so for Israel and for us because we have a copy of all of them at out fingertips. We should be better at obeying, but Christians get it wrong all the time. Maybe we don’t take the warnings to heart.
