2 Chronicles 6:32-33 NKJV
Moreover, concerning a foreigner, who is not of Your people Israel, but has come from a far country for the sake of Your great name and Your mighty hand and your outstretched arm, when they come and pray in this temple; then hear from heaven Your dwelling place, and do according to all for which the foreigner calls to You, that all peoples of the earth may know Your name and fear You, as do Your people Israel, and that they may know that this temple which I have built is called by Your name.
As Solomon prays to God about the temple he built he asked God to answer the prayer of strangers who came there as a result of hearing about the greatness of God. He wanted the prayers they made in that place be answered so strangers would become aware of God and revere Him like the Israelites did. The principle in prayer we can glean from this is we should pray for God to be glorified. Solomon wanted the people who did not know God to come to know Him. In all our prayers, our desire should be that when the prayer is answered God is glorified.
