From St. Isaac the Syrian

“………at every moment we should know that we stand in need of repentance throughout the twenty-four hous of the night and the day………….repentance is this: continual and intense supplication which by means of prayer filled with compunction draws nigh to God in order to seek forgiveness of past offenses, and entreaty for preservation from future ones.”  ~ from Homily Seventy of St. Isaac the Syrian
