2 Bible Verses about Goal Setting

What man among you if he wishes to build a tower does not first sit down and estimate the cost of it, to see whether he has enough to complete it? Or else when he has laid his foundation and cannot finish the building, everyone who sees it will begin to ridicule him, and say, 'This man started to erect a building, and could not finish it!'read more.
Or what king, if he is going to meet another king in battle, does not sit down first and consider whether he is able with ten thousand men to meet the other who is coming against him with twenty thousand?

This, instead of saying, "If it is the Lord's will, we shall live to do this or that." But, as it is, you pride yourselves on your pretensions. All such pride is wrong.
