That prayer to the Son and not the Father is most out of place and only to be suggested in defiance of manifest truth, one and all will admit. In prayer to both it is plain that we should have to offer our claims in plural form, and in our prayers say, "Grant you both, Bless you both, Supply you both, Save you both," or the like, which is self-evidently wrong and also incapable of being shown by anyone to stand in the scriptures as spoken by any.
It remains, accordingly, to pray to God alone, the Father of All, not however apart from the High Priest who has been appointed by the Father with swearing of an oath, according to the words He hath sworn and shall not repent, "You are a priest forever after the order of Melchizedek." In thanksgiving to God, therefore, during their prayers, saints acknowledge His favors through Christ Jesus.
Just as the man who is scrupulous about prayer ought not to pray to one who himself prays but to the Father upon whom our Lord Jesus has taught us to call in our prayers, so we are not to offer any prayer to the Father apart from Him. He clearly sets this forth himself when He says, "Verily, verily, I tell you, whatsoever you may ask of my Father He shall give you in my house. Until but now you have not asked aught in my name. Ask and you shall receive, that your joy may be fulfilled."
