Another important aspect of the Van Tillian apologetical program is the distinction between "proof" and "persuasion". According to the first chapter of the Epistle to the Romans, man has ample proof in all of creation of God's existence and attributes but chooses to suppress it. Van Til likewise claimed that there are valid arguments to prove that the God of the Bible exists but that the unbeliever would not necessarily be persuaded by them because of his suppression of the truth, and therefore the apologist, he said, must present the truth regardless of whether anyone is actually persuaded by it (Frame notes that the apologist is here akin to the psychiatrist who presents the truth about the paranoid's delusions, trusting that his patient knows the truth at some level and can accept it—though Frame, as a Calvinist, would say the special intervention of God in the Holy Spirit is also required for the unbeliever to accept ultimate truths.) An implication of this position is that all arguments are "person relative" in the sense that one non-Christian might be persuaded by a particular argument and another might not be, depending on their background and experiences; even if the argument constitutes logically valid proof.
