17 Those people may be paying you a lot of attention, but it isn't for your good. They only want to keep you away from me, so you will pay them a lot of attention.
18 It is always good to give your attention to something worthwhile, even when I am not with you.
19 My children, I am in terrible pain until Christ may be seen living in you.
20 I wish I were with you now. Then I would not have to talk this way. You really have me puzzled.
21 Some of you would like to be under the rule of the Law of Moses. But do you know what the Law says?
22 In the Scriptures we learn that Abraham had two sons. The mother of one of them was a slave, while the mother of the other one had always been free.
23 The son of the slave woman was born in the usual way. But the son of the free woman was born because of God's promise.
