Does God Hear the Prayers of All People?...or only the prayers of those who are His children through Jesus?

Does God hear the prayers of all people?It's an important question. Since the tragedy of 911 and most recently the terrible, insane massacre of 32 people at Virginia Tech, all kinds of prayer gatherings have taken place with representatives from virtually all major religions in the world today. There is an equilateral tone to whom God is and how we approach Him--prayer being the most easily demonstrative. Even nonbelievers may say out of sympathy or condolence for others, "our thoughts and prayers go with you" or "we are praying for you."The first Thrusday of May is the National Day of Prayer sanctioned by the government and has been practiced as early as 1775 that "designated a time for prayer in forming a new nation." Is heaven pleased with this kind of national acknowledgement? Does it accomplish anything for the kingdom of God? Is it biblically sanctioned? And can it bring glory to God if the prayers are not offered through Jesus Christ our Lord?What say you? Does God hear the prayers of all people of all religions? Before you answer, read these revealing words:

"For what is the hope of the godless when he is cut off, when God requires his life? Will God hear his cry, when distress comes upon him? Will he take delight in the Almighty; will he call on God at all times?" (Job 27:8-10)."The LORD is far from the wicked, but He hears the prayer of the righteous" (Proverbs 15:29)."We know that God does not hear sinners; but if anyone is God-fearing, and does His will, He hears him" (John 9:31).

Conclusion: Only the prayers of His own children through Jesus Christ our Lord, will the He ever hear (except the prayer of any sinner crying out for mercy and repentance to be saved from sin through the hearing of the gospel and the conviction of the Holy Spirit).
