It is a great good to give oneself up to the will of God. Then the Lord alone is in the soul. No other thought can enter in, and the soul feels God's love, even though the body be suffering.
The Resurrection of the Lord is the renewal of human nature, and the renewal, re-creation and return to immortality of the first Adam who was swallowed up by death because of sin, and through death went back to the earth from which he was formed.
