Luke 14:27-28
27 ^Whoever does not bear his own cross and come after me, cannot be my disciple. 28 ^For which of you, desiring to build a tower, does not first sit down and count the cost, whether he has enough to complete it? RSV
Whoever does not carry his own cross [expressing a willingness to endure whatever may come] and follow after Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me] cannot be My disciple.

For which one of you, when he wants to build a watchtower [for his guards], does not first sit down and calculate the cost, to see if he has enough to finish it?
