I think the enemy is threatened most by what he doesn’t have any more—a relationship with God, and the joy, peace, hope, and love that overflows from it. Even the best of his counterfeits are poor imitations in those areas, so he spends most of his time tempting you to build walls of bitterness, anxiety, despair, and fear.
Your breakthroughs will come more quickly when you refocus your attention to all you’ve been blessed with, rather than on what you don’t have, or on what others have done. Thankfulness and forgiveness are like battering rams to walls of negativity, opening your heart to Jesus, and dropping a million of bricks on the enemy’s stupid head.
