Do you think God listens to the prayers of the unsaved? My pastor friend posed a question about strange fire that was mentioned in Leviticus. Two of Aarons sons were excited to be newly advanced to the priestly service; they got carried away by their excitement, and stepped out of bounds by offering fire and incense to God, which was strictly forbidden by the law. It’s possible that on this day Aaron was the only one to perform such duties. My thoughts are that they wanted a bigger, more prestigious role, and because of their arrogance, God struck them down. That day, they had been appointed to assist, not lead, and God was not going to have it, and took them out.
Many people, who do not know the Lord, take for granted that he listens to them, even when they have no relationship with him. God has a particular order, and if you haven’t surrendered to Jesus, he can’t hear you. Aarons sons neglected God’s order and paid the price with their life. The same thing happens when the unsaved pray; they’ve neglected God’s particular order, so he can't hear them, and will pay the price unless they surrender to Jesus first. As Christians, we are of the priestly order, and can go to God because of our relationship with Jesus; he is our High Priest, and intercedes for us. We are not worthy to stand before God without him.
And fire came out from before the LORD and consumed them, and they died before the LORD. Leviticus 10:2
We know that God does not listen to sinners, but if anyone is a worshiper of God and does his will, God listens to him. John 9:31
