When You descended to death, O Immortal Life, * You slew Hades with the lightning of Your divinity. * And when You raised the dead from the depths of the earth, * all the heavenly Powers cried out: * “O Giver of Life, Christ our God, glory to You!” (Troparion)
Wisdom from the Church Fathers
Every day you provide your bodies with good to keep them from failing. In the same way your good works should be the daily nourishment of your hearts. Your bodies are fed with food and your spirits with good works. You aren't to deny your soul, which is going to live forever, what you grant to your body, which is going to die.
