2 Bible Verses about Goal Setting

For which of you wants to build a tower and does not first sit down to calculate the expense, to see if he has enough money to complete it? ??29 in case, after he has laid the foundation and then is unable to finish the building, all the spectators start to make fun of him, saying, 'This fellow started to build but he could not finish it.' Or what king sets out to fight against another king without first sitting down to deliberate whether with ten thousand men he can encounter the king who is attacking him with twenty thousand?

You ought rather to say, "If the Lord will, we shall live to do this or that." But here you are, boasting in your proud pretensions! All such boasting is wicked.
