A pre-requisite for salvation is believing in the Bible as the true Word of God unto us and, therefore, an accurate, untarnished revelation of God’s character and will. Otherwise, the god we choose to believe in would not be the God of the Bible, but the god of our own construct, as we piece together the parts of the Bible we like and discard the parts we do not like. Similarly, salvation by our self-constructed god would bear no resemblance to salvation defined in the Bible.
“Let Thy mercies come also unto me, O Lord, even Thy salvation, according to Thy word.” ~ Psalm 119:41
Consequently, the act of faith in accepting the prescription for salvation articulated by God in His Word, must also mean full acceptance of ALL other prescriptions in His Word: Full acceptance of even those truths that we find uncomfortable.
In other words, if I yield my will to God for salvation, then I must also yield my will to Him for everything else. God, by definition, cannot be right about one thing and wrong about another. Acknowledgment of God’s authority as Deity, cannot be compartmentalized.
Hence, my very cognition is, and must always be, open and subservient to God’s truth and dismissive of any other “truth”, including “truth” of my own invention.
Anything else is both cognitively and spiritually dissonant.
