2 Chronicles 6

 whatever prayer, whatever supplication is made by anyone, or by all Your people Israel, when each one knows his own burden and his own grief, and spreads out his hands to this temple:  then hear from heaven Your dwelling place, and forgive, and give to everyone according to all his ways, whose heart You know (for You alone know the hearts of the sons of men),  vv.29-30

Read chapter 6
Solomon is now praying for the people of Israel at the dedication of the temple.  His prayer repeats that the people turn to God in repentance and that God would hear and forgive.  The temple was a symbol of God's fullness where a person could go to seek the Lord.  In verses 29-30 it points out that that a person doesn't need to even go in to the temple to pray for to the Lord but to spread his hands toward the temple.  My first realization of the realness of Christ was when someone asked if they could pray for me on a Wednesday afternoon when I was on a roadside in the mountains.  I remember thinking it was weird as I thought people only prayed on Sundays and in church.  Boy am I glad that's not true as that prayer was heard by God and helped me become a believer in Jesus Christ and change my life forever.  I also think of the book of Daniel when he was about to be thrown in the lions den because he was found praying for his windows were open toward Jerusalem where the temple was and "And in his upper room, with his windows open toward Jerusalem, he knelt down on his knees three times that day, and prayed and gave thanks before his God, as was his custom since early days" (Daniel 6:10).  Now we don't have the temple to pray towards today but the beauty of God being everywhere and knowing our hearts that when we pray wherever we are, whether a believer or not (see verses 32-33), He hears us not only in corporate prayer but as individuals as well.  Have you been in an unlikely place to pray and experienced the Lord's answer?
