Galatians 4:1-??? Random thoughts

Not too sure where I am going to land in the verses listed below (see 10/8 entry). You can see the accented verses that are most interesting and provocative.

• elemental spirits -- sounds magical to me!
• fullness of time -- NOT the end of time -- interesting eschatology
• adoption
• Paul claims for himself "the pain of childbirth" -- whoa

Any ideas of what seems most interesting to you? I can see starting with verse 1 through 7, but where to stop?
