Heidelberg Q17 - Man cannot bear God's wrath

So, the redeemer must be both man and God.  Q16 talked about why he must be man.  Q17 digs deeper into why he must also be God...

Q17. Why must he in one person be also very God? A: That he might, by the power of his Godhead sustain in his human nature, the burden of God's wrath; and might obtain for, and restore to us, righteousness and life. Scripture Proofs: Isa.9:6, Isa.63:3-4, Isa.53:11, Deut.4:24, Nah.1:6, Ps.130:3, Isa.53:5, Isa.53:11, Acts 2:24, 1 Pet.3:18, John 3:16, Acts 20:28, John 1:4

...because a mere man couldn't bear God's full wrath
