2844. 'And not withheld your son, your only son' means the union of the Human and the Divine which was effected by means of the final degree of temptation. This is clear from what has been stated above in 2827, where the same words occur, except for the omission of 'from Me' in the present verse, which means that the union is to advance further still As regards the union of the Lord's Human Essence with His Divine Essence ever advancing until it was complete, see 1864, 2033.
