P. T. Forsythe, in the middle of a lecture on the work of Christ, gets to preaching, and it's pretty wonderful:

To deliver us from evil is not simply to take us out of hell, it is to take us into heaven. Christ does not simply pluck us out of the hands of Satan, He does so by giving us to God.

He does not simply release us from slavery. He commits us in the act to a positive liberty.

He does not simply cancel the charge against us in court and bid us walk out of jail, He meets us at the prison-door and puts us in a new way of life.

His forgiveness is not simply retrospective, it is, in the same act, the gift of eternal life. Our evil is overcome by good. We are won from sin by an act which at the same time makes us not simply innocent but holy.

In speaking of the reasons behind Christ's work, Forsythe has this insight....

 This obedience (of dying on the cross in our place) was the Holy Father's joy and satisfaction. He found Himself in it. And it was also the foiling and destruction of the evil power. And it was farther the creative source of holiness in a race not only impressed by the spectacle of its tragic hero victorious, but regenerate by the solidarity of a new life from its creative Head.

The work of Christ was thus in the same act triumphant on evil, satisfying to the heart of God....He subdued Satan,  rejoiced the Father, and set up in Humanity the kingdom — all in one supreme and consummate act of His one person. He destroyed the kingdom of evil...by actually establishing God's kingdom in the heart of it.

Peter flunked his test miserably, though warned by Jesus himself. Innocently warming his hands on a cold winter night, a young girl got him to deny Christ. But he repented, was forgiven, and soared when tested from that time on. 

Remember Micaiah, that mysterious prophet who appears only once in the Old Testament? When the kingdom was divided between north and south, the king of Israel decided to retake some lost land, and see if he could get Jehoshapht, the southern king, to join forces.

Jehoshapht was leaning towards co-operating, but listened to his gut (the Holy Spirit??) suggesting that they should inquire of the Lord. Suddenly 400 of Israel's "finest" prophets stood in front of him, saying the politically correct thing that their boss, the king of Israel, wanted them to say.

"Go," they answered, "for the Lord will give it into the king's hand." 1 Kings 22:6

In a very telling response that called into question the godly character of the 400 prophets in front of him, Jehoshaphat asked, "Is there not a prophet of the Lord here whom we can inquire of?

Ouch. The king of the north responded, obviously irritated, "yeah, there is one fellow, but I don't like him. He never prophesies anything good about me, only bad. His name is Micaiah.

Jehoshaphat insisted, and the despised prophet was sent for. The messenger who was sent for him told him on the way, in effect, "Look, for once, just fit in. Everybody has already agreed that we should go and get the land back, and that victory is assured. Please, I'm begging you, for your own sake, go with the flow."

The scene that followed is both hilarious and stunning, climaxing with the high priest Kenaanah slapping Micaiah around. It turns into sort of a "Oh, yeah? We'll see!" senario. Micaiah refused to let the situation intimate him, and predicted disaster, refusing to wilt under pressure. He did God proud. And ignoring sound advice, the king of Israel died in battle.

At the turn of the 20th Century, P. T. Forsythe was a theologian and pastor in demand on both sides of the Atlantic. Over several decades of ministry he had "jettisoned much he had valued in scholarship and biblical criticism in order to safeguard passionately the very core of the Gospel - the holiness of God, the sin of man, and the supreme value of the cross."

(Extracted from Memoir by his daughter in THE WORK OF CHRIST. She saw her father as a modern day Amos, with a vision of the Cross.)

What Forsythe was attempting to passionately safeguard was the atoning work of the Cross. Recent scholarship had chipped away at the view that a holy God was reconciling a lost mankind to himself by pouring out his wrath on his Son, who had agreed to pay the penalty in our place. "Conventional wisdom"  determined that it was time to move on from such archaic beliefs.

In  1899, he gave an address at the second decennial International Congregations Council, on the theme of "The Evangelical Principle of Authority, and began with a shocker of a first sentence.

"The Cross is the final seat of authority, not only for the Church, but for all human society." This was his Micaiah moment. His daughter says that it created such a fervor the the vast audience was at first silent, but then almost spontaneously turned its long applause into the singing of the hymn (which Forsythe suggested) "In The Cross Of Christ I Glory."

Wouldn't you have loved to have been there? Surely all of heaven sang along. And if you listened closely, heaven's applause was mixed in with earthly applause, as the atoning work of our Gracious God was lifted up and exalted.

In the cross of Christ I glory,
Towering o’er the wrecks of time;
All the light of sacred story
Gathers round its head sublime.

When the woes of life o’ertake me,
Hopes deceive, and fears annoy,
Never shall the cross forsake me,
Lo! it glows with peace and joy.

When the sun of bliss is beaming
Light and love upon my way,
From the cross the radiance streaming
Adds more luster to the day.

Bane and blessing, pain and pleasure,
By the cross are sanctified;
Peace is there that knows no measure,
Joys that through all time abide.

In the cross of Christ I glory,
Towering o’er the wrecks of time;
All the light of sacred story
Gathers round its head sublime.
