I and the lad will go yonder and worship, and come again to you.
Abraham and Isaac went to perform the highest act of worship that a father has been called upon to perform - to offer his own son in sacrifice to God. This was Abraham’s ultimate test. Would he go through with it? You know he did. Abraham, “the friend of God,” one who acted in faith all his life seemed to know that somehow God would give Isaac back. And He did! A substitute was found! But there was no substitute for God’s Son. Doesn’t that make you want to worship?
