A parabola is a symmetrical curve on a plane that is shaped like the letter, “U.” To be more technical, it the locus of points on a plane equidistant from a point and a line. It has the general formula:
y = ax² + bx + c
The standard parabola (like the picture above) reaches from infinity on the left to infinity on the right. The further left you go, the higher the shape. The further right you go, the higher the shape.
This shape is a bit like the life of Jesus. He with with God from the beginning (John 1:1). Jesus was in glory with the Father. He was as high as one could be in the universe. But when he came into the flesh, he descended. In fact, he descended as far as anyone has gone before. He “emptied himself” and “was born in the likeness of men” (Philippians 2:7). He then died a despicable death on the cross (Philippians 2:8). But God raised him from the dead and “highly exalted him” (Philippians 2:9). Jesus now sits with the Father at his right hand (Psalm 110:1). Jesus is, once again, restored to his former glory (John 17:5).
A parabola is a good graph of the life of Jesus Christ.
