Luke 14:27-30

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? Otherwise, when he has laid a foundation and is unable to finish [the building], all who see it will begin to ridicule him, saying, ‘This man began to build and was not able to finish!’
