“Sanctify them through thy truth: thy word is truth” (John 7:17).
This scripture should be the criterion for anyone studying the Bible. A person who wills to do the will of God has that capacity of the mind. In Romans 7 Paul tells the capacity of his mind—the ability of the mind—thelo and thelema. The mind can and will to do either good or evil. In repentance there is the new mind that wills to do the will of God and serve God as described in Romans 7:25.
