We come now to the conclusion of Conference 19 where Cassian and Germanus question Abba John about how one overcomes and does battle with vices that reemerge after the solitary life of the anchorite has been embraced. Abba John describes for them how they must engage in a kind of mental warfare - drawing the vices they see active in their hearts to mind and allowing themselves to be humbled by them and then apply the necessary reparation that is need; that is, apply the healing balm of penance and self rebuke to uproot the vestiges of these sins. The self-honesty as well as the self-awareness necessary for such an undertaking is great, especially since it is done without the support and guidance of others. The only vice where this is not to be done is fornication or unchastity. Since such vices arise out of and are connected to bodily appetites, the use of mental imagery could be very dangerous and simply draw one further into sin.
Lengthy discussion ensued about renewing the asceticism that would even allow this kind of mindfulness and purity of heart to develop. In particular, the group discussed the importance of fasting in the humbling of mind and body and allowing one to recognize one's dependence on God. We must come to see once more the necessity of such practices, develop the resolve to embrace them, and take them up with love; acknowledging that they bring us freedom and draw us closer to Christ.
We also spoke at length about the importance of not receiving the grace of God in vain. When receiving the grace and mercy of God through confession of our sins, we must take up the means available to us to repair the damage that the sin has inflicted; to uproot the vice and apply the healing balm.
