Prayer offered to God in truth is imperishable. Now and then we may forget what we have prayed about but God preserves our prayer for ever. On the Day of Judgment all the good that we have done during our lives will stand at our side, to our glory. And vice versa: the bad, if unrepented, will condemn and cast us into outer darkness. Repentance can obliterate the effects of sin. By Divine power life may be restored in all its plenitude – not, however, by unilateral intervention on God’s part but always and only in accord with us. God does nothing with man without man’s co-operation.
Saint Sophrony, His Life Is Mine
