Who is the real Isaac?

Abraham's offering of his beloved and only son, Isaac, on the altar is a vivid picture of God the Father's offering of His beloved and only Son, Jesus Christ, on the cross.
In this picture Isaac typifies Christ in a detailed way. Isaac, as Abraham's only son (vv. 2, 12, 16), typifies Christ as God's only begotten Son (John 3:16).
Isaac was Abraham's beloved son (v. 2), and Christ was the Father's beloved Son, in whom He delighted (Matt. 3:17). Isaac took his father's will (v. 6), and Christ also chose the will of His Father (Matt. 26:39).
Isaac was obedient unto death (vv. 9-10); likewise, Christ was obedient unto death (Phil. 2:8). Isaac carried the wood for the burnt offering and walked to the top of Mount Moriah (v. 6); in the same way, Christ bore His cross and walked to Golgotha (John 19:17).
Isaac was offered to God as a burnt offering on Mount Moriah; Christ also was offered to God on the same mountain (see note 11 in Mark 10) to fulfill the type of the burnt offering.
Isaac was "killed" on the altar and was returned to Abraham on the third day, that is, in resurrection (vv. 4, 10-13; Heb. 11:19); similarly, Christ was crucified on the cross and was resur­rected on the third day (1 Cor. 15:4).
Isaac was multiplied in resurrection (v. 17), and Christ also was multiplied in His resurrection (John 12:24; 1 Pet. 1:3). Isaac was the seed of Abraham for the blessing of all the nations (v. 18); likewise, Christ is the unique seed of Abraham in whom the bless­ing of Abraham has come to the nations (Gal. 3:8, 14, 16).
