Notice the contrasts Paul uses:
v6 Spiritual Israel vs. National Israel
v7 Isaac vs. Ishmael
v10 Jacob vs. Esau
v11 (this was not because of moral excellence, not merit)
v17 God's power vs. Pharaoh
v21 Vessels of glory vs. Vessels of dishonor (who did this? God!)
v22

Some important terms:

Acts 2:23 - "predetermined plan" is tied together with "foreknowledge". The definite article "the" when used in the manner as it is used here ''the predetermined plan and (the) foreknowledge"; the tying word "and" comes to mean "even" because of the "Granville Sharp" rule.
