The earth is cold, hard, dead and frozen.
A blanket of beautiful snow covers the earth. How glorious and wonderful! But merely external as the ground beneath is still cold, hard, dead and frozen, revealed by the melting snow.
Our souls, dark and depraved; seeking after pleasures that only lead to pain or even death.
Religion, a blanket of good works and deeds that look so beautiful and wonderful. But merely external as the soul beneath is still dark and depraved, revealed with time.
