The Lord Jesus had been revealing Himself to Nathaniel and this conversation took place near Bethel, so that the reference to Jacob's ladder was very forcible and the wonderful type was made clear.
When Jesus said that heaven would be opened, He meant not only opened just once, but remaining open; so that ever since Christ ascended into heaven we have lived and are still living under an "open heaven," which means free intercourse between God and man, because Christ Himself is the Ladder. It also means He is the one and only means of communication between the sinner and God. It is "through Him we have access by one Spirit unto the Father." [Footnote: Eph. ii. 18.] All that we know of God comes to us through Him, and all the grace we receive from God comes through Him. So Jacob's ladder is as real to us now as it was to him then, for it connects the seen with the unseen. It is possible for us now to have Christ's Presence with us always and everywhere, for He says Lo, I am with you alway. [Footnote: Matt. xxviii. 20.]
But there was something more wonderful for Jacob to see even than the ladder. "The LORD stood above the ladder." It was the first time in his life he had realised the Presence of God. He had lived over forty years without realising that God was close to him. When he awoke from his dream he said, "Surely the Lord is in this place and I knew it not." He never forgot it, just as we never forget the time and place where we are converted. One hundred years after that night, when he was a very old man, he mentioned it to his son. He said to Joseph, "God Almighty appeared unto me at Luz and blessed me." [Footnote: Gen. xlviii. 3.]
But what impressed him deeply was that there in that lonely place, many miles away from any human being, he heard the Voice of God speaking to him. It was then that a new life began in his soul, for God told him that from that moment He would be with him everywhere, blessing him and protecting him from all danger, and it was then Jacob began to trust God as his God.
So we see how God's glory and God's grace were shining down from the top of the ladder into poor Jacob's heart. Jacob was face to face with God for the first time, and he began to tremble with fear. If only you could realise that God is now, at this very moment, straight in front of you, you would fall down on your face before Him, and you would cry to Him as Job did, "I have heard of Thee by the hearing of the ear, but now mine eye seeth Thee; wherefore I abhor myself and repent in dust and ashes." [Footnote: Job xlii. 5, 6.]
It is at this moment that we realise for the first time our need of a substitute, just as Job did, for he said, "He is not a man as I am that I should answer Him, neither is there any daysman betwixt us that can lay His hand upon us both." [Footnote: Job ix. 33.] How Job would have rejoiced in the glorious revelation which Christ has brought to us. "There is one God, and one Mediator between God and men, the Man Christ Jesus, Who gave Himself a ransom for all." [Footnote: 1 Tim. ii. 5, 6.] He is not only the Mediator laying His hand upon us both, but He gave Himself, that is, He gave His life as a ransom. The ransom price was His own precious blood, for the life is in the blood. It is the Blood of God's own dear Son which makes an atonement for the soul.
The sentence passed on you and me and on every sinner is the sentence of death, for death is the penalty for sin. We are all under the sentence of death, but the glorious message is sent God has found a Substitute.
"He bore on the tree the sentence for me,
And now both the Surety and sinner are free."
You and I now have what Job longed for so earnestly. The Daysman is the Son of God Himself, "Whom God hath set forth to be a propitiation," that is an atoning sacrifice, "through faith in His Blood." [Footnote: Rom. iii. 25.]
At first Jacob trembled with fear, but after he had heard the loving words which God spoke to him from the top of that wonderful ladder, then he began to realise that he was no longer alone in that lonely place. He said, "This is the house of God, this is the gate of heaven." Earth had faded from his sight and he was surrounded by heavenly realities. And so it is now, the veil is very thin which separates earth from heaven, the temporal from the Eternal.
