Being His Disciplined

Now great crowds were traveling with Him. So He turned and said to them: “If anyone comes to Me and does not hate his own father and mother, wife and children, brothers and sisters—yes, and even his own life—he cannot be My disciple. Whoever does not bear his own cross and come after Me cannot be My disciple.
“For which of you, wanting to build a tower, doesn’t first sit down and calculate the cost to see if he has enough to complete it? Otherwise, after he has laid the foundation and cannot finish it, all the onlookers will begin to make fun of him, saying, ‘This man started to build and wasn’t able to finish.’
“Or what king, going to war against another king, will not first sit down and decide if he is able with 10,000 to oppose the one who comes against him with 20,000? If not, while the other is still far off, he sends a delegation and asks for terms of peace. In the same way, therefore, every one of you who does not say good-bye to all his possessions cannot be My disciple.

Being a disciple means being under a certain discipline. If you are going to study the stars, you must learn to work at night. If you are going to be strong, you must learn to exercise. If you are going to design computers, you must learn code. He was not teaching about “going to heaven.” He was teaching His listeners how to live in a way that was under His discipline, and therefore, useful in the earth. Discipline is required if we desire to be good citizens of Heaven (while still on the earth).
