Today's Biblical Theology Lecture in a Sonnet

The Glory of God is a blinding light,
Jesus allows men to escape darkness.
How can a person claim to be the truth?
God is showing how He invades humans;
Jesus belongs to God, He is from God,
The door and the gate for His Father's Sheep.
Truly, truly is divine sign language.
The vine is the true way to salvation;
Salvation is Jesus' revealing of God;
Jesus is saying saving is God's thing.
They are one; But what kind of unity?
Essential, of essence? Ethics, of acts?
They're the same, as is function; that's unique!
What is the meanin of these mysteries?
