It might not have a strict poetic form that we might otherwise be used to, but this is the most prominent of poems about our Lord Jesus. Remember that Jesus was not only a baby in a manger or a dying man on a cross, but was also the Lord of Heaven and Earth—has always been, and will always be.

He is the image of the invisible God,
the firstborn of all creation.
For by him all things were created,
in heaven and on earth,
visible and invisible,
whether thrones or dominions
or rulers or authorities—
all things were created through him and for him.
And he is before all things,
and in him all things hold together.
And he is the head of the body, the church.
He is the beginning,
the firstborn from the dead,
that in everything he might be preeminent.
For in him all the fullness of God was pleased to dwell,
and through him to reconcile to himself all things,
whether on earth or in heaven,
making peace by the blood of his cross.

Colossians 1:15-20 (ESV)
