Contradiction with Proverbs 28:9
Contradicts with 1 Samuel 7:9 as it implies God does not listen to the prayers of those who turn from the law, yet God heeds Samuel's sacrifice and prayer.
Proverbs 28:9: He that turneth away his ear from hearing the law, even his prayer [shall be] abomination.
Contradiction with Isaiah 1:15
Suggests God will not hear prayers when hands are full of blood, which contradicts God responding to Samuel's offering.
Isaiah 1:15: And when ye spread forth your hands, I will hide mine eyes from you: yea, when ye make many prayers, I will not hear: your hands are full of blood. [make...: Heb. multiply prayer] [blood: Heb. bloods]
Contradiction with John 9:31
States that God does not listen to sinners, while 1 Samuel 7:9 shows God responding to Samuel despite him being a human prone to sin.
John 9:31: Now we know that God heareth not sinners: but if any man be a worshipper of God, and doeth his will, him he heareth.
Contradiction with James 4:3
Indicates that prayers can be unanswered because of wrong motives, contrasted by God's immediate action following Samuel's plea.
James 4:3: Ye ask, and receive not, because ye ask amiss, that ye may consume [it] upon your lusts. [lusts: or, pleasures]
