Tertullian

“ He surely, by thus teaching us the proper discipline of prayer, has determined that that God must be prayed to from whom men were to receive this discipline of prayer—whether condemnatory of pride, or justifying in humility. ”

“ Whosoever wishes to see Jesus the Son of David must believe in Him; through the Virgin’s birth. [34] He who will not believe this will not hear from Him the salutation, “Thy faith hath saved thee.” And so he will remain blind, falling into Antithesis after Antithesis, which mutually destroy each other, [35] just as “the blind man leads the blind down into the ditch.” ”

“ All Proofs of Christ’s Relation to the Creator, Marcion’s Antithesis Between David and Christ Confuted.
When He recommends perseverance and earnestness in prayer, He sets before us the parable of the judge who was compelled to listen to the widow, owing to the earnestness and importunity of her requests. [1] He show us that it is God the judge whom we must importune with prayer, and not Himself, if He is not Himself the judge. ”
