The first condition necessary in order to deny that is absolute faith.
Quotes about self-denial
From the speeches of Sun Myung Moon and Hak Ja Han
Not only must you deny yourself hundreds of times, but you must move up to a position where you are able to love your enemy. Unless you do that, you cannot stand on God’s side.
If you deny yourself and put God in the center of your thinking and your life, Satan will no longer control you; instead God will come to you and take charge of you.
