So the two of them went together.
There is a great mystery illustrated here: the mystery of the cross. Twice in this chapter we are told that Abraham the father, and Isaac the son, went both of them together to the place of sacrifice, the place where the only begotten son (Hebrews 11:17) was to be offered up, though at the last, as one has well said, “God spared that father’s heart a pang He would not spare His own.” So throughout all the ages it might be said of the eternal Father and the eternal Son, that they went both of them together. The cross was ever before God. Christ was delivered to death by the foreknowledge of God. Redemption was planned and provided for, long before sin lifted up its ugly head to mar God’s fair creation. All down the centuries the Father and the Son counseled together concerning the great redemption there to be wrought out.
Son of God, Thy Father’s bosom
Ever was Thy dwelling-place,
His delight, in Him rejoicing,
One with Him in power and grace.
Oh, what wondrous love and mercy!
Thou didst lay Thy glory by.
And for us didst come from heaven,
As the Lamb of God to die.
