BIG IDEA: You are spiritual Isaacs!
*Three distinctions the law illustrates about spiritual Isaacs:

1) The Reality: Those of the Covenant of promise are born into freedom (not
slavery). (v.21-26)

2) The Reason: Those of the Covenant of promise are born according to the
Spirit (not according to the flesh). (v.27-28)

3) The Result: Those of the Covenant of promise are born as sure heirs (not as
cast outs). (v.29-31)
