Whether sinners impetrate anything from God by their prayers?

❌ Objection 1 : It would seem that sinners impetrate nothing from God by their prayers. It is written (Jn. 9:31): "We know that God doth not hear sinners"; and this agrees with the saying of Prov. 28:9, "He that turneth away his ears from hearing the law, his prayer shall be an abomination." Now an abominable prayer impetrates nothing from God. Therefore sinners impetrate nothing from God.

❌ Objection 2 : Further, the just impetrate from God what they merit, as stated above (Article [15], ad 2). But sinners cannot merit anything since they lack grace and charity which is the "power of godliness," according to a gloss on 2 Tim. 3:5, "Having an appearance indeed of godliness, but denying the power thereof." and so their prayer is impious, and yet piety it required in order that prayer may be impetrative, as stated above (Article [15], ad 2). Therefore sinners impetrate nothing by their prayers.

❌ Objection 3 : Further, Chrysostom [*Hom. xiv in the Opus Imperfectum falsely ascribed to St. John Chrysostom] says: "The Father is unwilling to hear the prayer which the Son has not inspired." Now in the prayer inspired by Christ we say: "Forgive us our trespasses as we forgive them that trespass against us": and sinners do not fulfil this. Therefore either they lie in saying this, and so are unworthy to be heard, or, if they do not say it, they are not heard, because they do not observe the form of prayer instituted by Christ.
