Each person of the Godhead is truth, and while the scripture is often pointing to redemptive truth, i.e. the truth of the gospel that saves sinners, yet there is a sense in which Christ as God has a monopoly on all truth.
All the laws of logic and observable truths in the universe have been created by Jesus Christ. Colossians 1:16 says, “all things were created by him, and for him.” So while God has revealed Himself in a special way through scripture, He has also revealed Himself in nature which we call general revelation.
So any truth that is discoverable through nature, like the laws of logic, has been given by God and any truth we discover can only be discovered because has so ordered those truths that we should discover them. But there is no truth completely detached from or unrelated to God.
