The Bible says the devil is the source of all temptation; he is called “the tempter” in Matthew 4:3. But he is able to succeed only because we let him, and we let him succeed because of our own weakness. This is one reason why we need Christ. Only He can forgive us when we sin, and only He can give us the strength, by the power of His Holy Spirit, to resist temptation. And in His encounter with the devil at the beginning of His ministry He pointed the way to victory: Using the truth of God’s Word to counteract Satan’s lies. Three times Satan attacked Him with almost overwhelming temptations, and three times Jesus replied with Scripture. - Matthew 4:10-11
