Carl R. Trueman (Reformed) wrote the following when discussing Jesus' role as heavenly intercessor:
Prayer is a means of grace because the economy of
grace involves the intercession of Christ. That intercession, even now, is what
makes God’s grace a potent reality to individual Christians. The consubstantiality
of Father and Son—that the Son is divine as the Father is divine, and both are
one God—means that the Son’s intercession will always be heard by the Father
and always answered in the affirmative. Were it not to, we could not say that
the two are one God. (Carl R. Trueman, Grace Alone Salvation as a Gift of
God: What the Reformers Taught . . . and Why it Still Matters [Grand
Rapids, Mich.: Zondervan, 2017], 221, emphasis added)
This
is why Jesus' prayer in the Garden of Gethsemane is anti-Trinitarian in nature:
Saying, Father, if thou be willing, remove this
cup from me: nevertheless not my will, but thine, be done. (Luke 22:42)
Jesus
did not get what he prayed for; appealing to Jesus praying in his human nature
merely, not only is Nestorian in nature (making a distinction between the
person of Jesus and his human nature) but rejects the consubstantiality of the
Father and the Son.
