Become A Real Son Of God - Prabhupada 0790
700103 - Lecture SB 06.01.06 - Los Angeles
One who is simply taking from father, "O God, give us our daily bread," and He is supplying, and eating and enjoying sense enjoyment, he is not real son. The real son is he who sacrifices his life for glorifying his father.
Similarly, anyone who will sacrifice his life . . . of course, it is not required that everyone shall be crucified like Lord Jesus Christ, but he should sacrifice his energy for the Supreme Lord. And that person who has devoted his energy for the satisfaction of the Supreme Lord, he is called Kṛṣṇa conscious person.
