Rebelling as we do against God through the passions and agreeing to pay tribute in the form of evil to that cunning tyrant and murderer of souls, the devil, we cannot be reconciled with God until we have first begun to fight against the devil with all our strength. for even though we assume the name of faithful Christians, until we have made ourselves the devil’s enemies and fight against him, we continue by deliberate choice to serve the shameful passions. And nothing of profit will come to us from our peace in the world , for our soul is in an evil state, rebelling against its own Maker and unwilling to be subject to His kingdom. It is still sold into bondage to hordes of savage masters, who urge it towards evil and treacherously contrive to make it choose the way which leads to destruction instead of that which brings salvation.
~St Maximos the Confessor
