Genesis 22:5

And Abraham said unto his young men, Abide ye here with the ass, and I and the lad will go yonder and worship, and come again to you. Although the servants of Abraham were devoted to him, they were hardly prepared to witness the scene which would be enacted on the mountain that lay before them. In spite of the fact that the outcome of his act of worship was hidden from Abraham, his faith clung to the promise of the Lord, accounting that God was able to raise up Isaac, even from the dead, Hebrews 11:17. For that reason he confidently says: We shall return to you. True faith trusts in God even when He seems harsh and angry, when the believer feels only His displeasure in his heart; for it is an easy matter for God to replace everything that He sees fit to take away, to bring back even that which was lost.
