It is not only sin that is terrifying, but also the despair and defection bred by sin. Isaac the Syrian has this to say concerning such a condition: ‘Have no fear, even though you fall daily; do not abandon prayer; stand up courageously, and the angel who watches over you will honor your patience.’ Let us recall the words of Christ in such cases, ‘Go and sin no more.’ And that is all–no curses, no excommunications. We must not submit to the evil spirit of dejection that seeks to draw us ever deeper into sin. Again and again, we must fall at Christ’s feet, again and again He will accept us.
