Commentaries:
Self-indulgence leads to excessive striving for yet more worldly pleasure. For those whose chief aim in life is sensual pleasure, there is never enough to satisfy. Self-indulgence can lead to full-blown addiction. Without God's truth of the coming resurrections of mankind, men see no reason to refrain from a life of pleasure and dissipation, ending in death.
