St. Isaac once again teaches us that we must fully and wisely engage in the spiritual battle - fighting on the right battlefield and making use of the right remedies to heal wounds. He warns us never to treat any sin as slight; for ignoring any sin will eventually make it our master.
Above all we must not be overly confident in our own strength but rather trust in divine providence and the manifestation of that providence in God's angels. They are always there interceding for us, revealing our enemies and fortifying us in the struggle. They show us how close God is to us.
