Satan cannot hear our prayers; only God has the ability to do so. While Satan is a keen observer of human behavior and may be aware of the general nature of our lives, he is not omniscient and cannot access the specific content of our prayers. The Bible shows that Satan operates under God's ultimate authority, and his powers are limited compared to God's infinite strength. The prayers of believers are directed to God alone, who hears them and responds according to His will. Regardless of Satan's awareness or lack thereof, our prayers remain potent expressions of faith and are securely within the realm of God’s sovereignty and grace.
In the end, it doesn't really matter if Satan and his demons can hear our prayers. We can talk to our Heavenly Father any time, and, if the devil overhears, that's fine. Our Father is able to accomplish His will, no matter what Satan does. The prophet Daniel was surrounded by physical and political enemies who were watching his every move, and what did he do? "He went to his house where he had windows in his upper chamber open toward Jerusalem. He got down on his knees three times a day and prayed and gave thanks before his God, as he had done previously" (Daniel 6:10). It did not matter that his enemies were watching and listening. He prayed. Just as the prophet Daniel remained steadfast in prayer despite the scrutiny of his enemies, we, too, should approach God with unwavering trust and devotion. Our prayers are not diminished by the presence of opposition; rather, they are an expression of our faith in the One who holds ultimate authority. So, let us pray boldly, knowing that God's plans prevail, and His grace is sufficient. Satan cannot hear our prayers, but God can.
