God and Satan each have a design, a battle plan, to capture our heart's devotion. The intimacy, beauty, and adventure of the Sacred Romance are placed and nurtured in the deepest longings of our heart by God himself. God's grand strategy, birthed in his grace toward us in Christ, and nurtured through the obedience of disciplined faith, is to release us into the redeemed life of our heart, knowing it will lead us back to him even as the North Star guides a ship across the vast unknown surface of the ocean.
If we were to find ourselves living with total freedom, Jesus informs us through his summary of the law in Luke 10:26-28, we would find ourselves loving God with all of our heart and our neighbors as ourselves. Jesus said further, "You will know the truth [me], and the truth will set you free."
The Enemy knows this as well, and his strategy to capture us is simply the opposite: to disconnect us from our heart and the heart of God toward us by any means possible. It is what he no doubt had to do to his own heart to bear the loss of heaven.
