I think sometimes of the Gospel as a four-legged stool. If you have only three legs, you fall; and even if you have all four, lean to hard in one direction and you fall.
In this analogy, the four legs of the Gospel are: the Incarnation, the Cross, the Resurrection, and the Ascension.
In the Incarnation, we see the Creator who so loves us that He comes down from heaven, humbles Himself to become one of us.
In the Cross, we see God dying on our behalf, making Himself the atoning sacrifice for our sins.
In the Resurrection, we see the Christ conquering the grave, creating a pathway whereby via faith we can follow Him into the inheritance of eternal life.
In the Ascension, we see Jesus returning to and preparing His Kingdom, which will one day come down to earth.
You must have all four legs of the stool in order for it to stand; but neither can you lean too hard in one direction or the other.
Ignore the Incarnation and you lose a good portion of God's love and His role as our mediator who is one just like us; lean too hard on the Incarnation leg and you fall into the heresy of a loving baby-Jesus who is completely safe and full of warm-fuzzies.
Ignore the Cross and you lose that Jesus was the willing Lamb of God, dying on our behalf and wiping out our sins; lean too hard on the Cross and you get a cold, punishing God who punishes the innocent in the most painful way possible.
Ignore the Resurrection and you lose eternal life and the defeat of death; lean too hard on the Resurrection and you fall into Gnosticism, the spirit-God who didn't really get tempted as we were tempted and didn't really suffer a painful death on the Cross.
Ignore the Ascension and you lose Christ the King, who may save by grace through faith but still expects obedience and maturity from His subjects; lean too hard on the Ascension and you get a distant and sovereign King rather than a loving Father-God.
You need all four legs, equally balanced. Because all four are part of the Gospel of Jesus Christ. The story of Jesus cannot be told without these four. The story of Jesus is all of the above: the babe in the manger, the sacrificial lamb, the conqueror of death, and the returning King. Anything short of these four, or too strongly leaning into one at the exclusion of the others, is bound to lead you astray.
