And whoever does not bear his cross and come after Me cannot be My disciple. “For which of you, intending to build a tower, does not sit down first and count the cost, whether he has enough to finish it--“lest, after he has laid the foundation, and is not able to finish, all who see it begin to mock him, “saying, ‘This man began to build and was not able to finish.’ “Or what king, going to make war against another king, does not sit down first and consider whether he is able with ten thousand to meet him who comes against him with twenty thousand? “Or else, while the other is still a great way off, he sends a delegation and asks conditions of peace. “So likewise, whoever of you does not forsake all that he has cannot be My disciple.—Luke 14:27-33
Consider the cost...yes. Also, consider the cost of not following Him. It is greater.
For what profit is it to a man if he gains the whole world, and loses his own soul? Or what will a man give in exchange for his soul?
Those who trust in their wealth
And boast in the multitude of their riches,
None of them can by any means redeem his brother,
Nor give to God a ransom for him--
For the redemption of their souls is costly,
And it shall cease forever--
That he should continue to live eternally,
And not see the Pit.—Psalm 49:6-9
Self-sacrifice: laying aside one’s personal interest or well-being for the sake of another
Let no one seek his own, but each one the other's well-being.—1 Cor 10:24
does not behave rudely, does not seek its own, is not provoked, thinks no evil;—1 Cor 13:5
Let each of you look out not only for his own interests, but also for the interests of others.—Phil 2:4
For whoever desires to save his life will lose it, but whoever loses his life for My sake will find it.—Matt 16:25
Jesus said to him, "If you want to be perfect, go, sell what you have and give to the poor, and you will have treasure in heaven; and come, follow Me."—Matt 19:21
It is good neither to eat meat nor drink wine nor do anything by which your brother stumbles or is offended or is made weak.—Romans 14:21
