I agree with the post above. Except that I would add that it helps to go offensively rather than defensively. That is, keep Bible verses going in your mind, and on your lips, at every reasonable opportunity.
The Bible says that the Word is a hammer that breaks the rock. In Psalm one we are told that those who meditate on the word day and night, and that is no exaggeration, are the ones who will be greatly blessed.
Singing scripture and praises is also a powerful form of spiritual warfare. When David sang to Saul evil spirits fled. Paul and Silas were miraculously released from prison when they were singing praise songs. When multiple armies came against little Israel, King Jehoshaphat sent out priests before the armies, singing praises. The armies turned on one another and killed one another.
On YouTube there are many places where you can find scripture only songs and also spoken Bible promises videos.
I pray for your peace and for your house.
