Redeeming The Time

The way of the cross, foolishness, the power of God, the secret to happiness, and the connection of the cross to the Dormition Fast. "The preaching of the Cross is to those who perish foolishness; but unto us who are saved, it is the power of God." What is this foolishness, and what is this power? Also a connection between the beginning of the Dormition Fast and the Procession of the Cross. Also a "secret" to obtaining happiness. 1 Corinthians 1:18-24
