Verse 3Sarah Sarah, type of grace, "the freewoman," and of the "Jerusalem which is above." See Genesis 17:15-19; Galatians 4:22-31 2 Isaac is typical in fourfold way: (1) of the Church as composed of the spiritual children of Abraham Galatians 4:28. (2) of Christ as the Son "obedient unto death" Genesis 22:1-10; Philippians 2:5-8. (3) of Christ as the Bridegroom of a called-out bride see Gen 24; also, "Church," Matthew 16:18,(See Scofield "Matthew 16:18") . (4) of the new nature of the believer as "born after the Spirit" Galatians 4:29. Verse 17angel(See Scofield "Hebrews 1:4") . Verse 33everlasting God (1) The Hebrew "Olam" is used in Scripture: (a) of secret or hidden things (e.g. Leviticus 5:2 "hidden"; 2 Kings 4:27, "hid"; Psalms 10:1, "hidest"); (b) an indefinite time or age Leviticus 25:32, "at any time"; Joshua 24:2 "in old time"). Hence the word is used to express the eternal duration of the being of God, Psalms 90:2. "From everlasting to everlasting"), and is the Hebrew synonym of the Greek "aion," age or dispensation. (See Scofield "Genesis 1:26") , note (4). (2) The ideas therefore of things kept secret and of indefinite duration combine in this word. Both ideas inhere in the doctrine of the dispensations or ages. They are among the "mysteries" of God Ephesians 1:9,10; 3:2-6; Matthew 13:11. The "everlasting" God (El Olam) is therefore that name of Deity in virtue of which He is the God whose wisdom has divided all time and eternity into the mystery of successive ages or dispensations. It is not merely that He is everlasting, but that He is God over everlasting things.
