And this depends on our practice of religion. It is by religion that we fulfill the purpose for which we were created. By believing what God has revealed, we know God. By knowing God, we cannot help but love Him. By practicing what we learn and obeying God's commands, we serve Him.
Many people spend their lives in a vain pursuit of riches, honors, and pleasures.
But these never satisfy the heart of man even on earth. Besides, they have to be left behind when the hour of death comes. Men learn to know, love, and serve God from Jesus Christ, the Son of God, Who teaches us through the Catholic Church. The study in which Jesus Christ teaches us about God and how to know, love, and serve Him, is the study of Religion. It is the most important study anyone can undertake.
