'Hard' in the Bible

But we give the good news of Christ on the cross, a hard thing to the Jews, and a foolish thing to the Gentiles;

If you get married it is not a sin; and if an unmarried woman gets married it is not a sin. But those who do so will have trouble in the flesh. But I will not be hard on you.

Now I say this for your profit; not to make things hard for you, but because of what is right, and so that you may be able to give all your attention to the things of the Lord.
