Wow, what a prayer! Solomon acknowledges God鈥檚 faithfulness in keeping his promises to David and asks him to continue to do that. He realizes Israel is going to fail to keep their commitments to God and wants God to forgive them when they turn from their sin and pray. He also sees that people who are not Israelites will come to worship God when they see how God blesses Israel.
We can pray similar things, but don鈥檛 need a temple. God dwells in us and is ready to keep his promises, forgive and attract others to himself through us.
