According to Scripture every part of the Bible is inspired.

A.D. 160-190. During this period we have several productions which employ the usual phrases in regard to the subject, such as "everlasting fire," "eternal punishment," and their equivalents. The last date brings us to the distinguished IRENAEUS, bishop of Lyons, in France. He taught that the wicked would be cast into And yet he did not believe that they would be punished endlessly, for he undoubtedly adopted the doctrine of the final annihilation of the disobedient and unrighteous. He says: "The principle of existence is not inherent in our own constitutions, but is given us of God; and the soul can exist only so long as God wills. He who cherishes the gift of existence, and is thankful to the Giver, shall exist forever; but he who despises it, and is ungrateful, deprives himself of the privilege of existing forever."..."He who is unthankful to God for this temporal life, which is little, cannot justly expect from him an existence which is endless."

Premodern Practiceand Doctrine of Scripture

Since the doctrine of inspiration is often denied, it calls for special consideration.

The doctrine of verbal inspiration is fully warranted by Scripture.

These seem to be the steps forward, the method of growth, which marked the reception of the old Pagan doctrine into the faith of the Christians. And the great wonder is that, considering the extent to which this dogma was received among both Jews and heathens, it did not get foothold in the church before; especially when we remember how rapidly other philosophical speculations and Pagan notions prevailed to the corruption of the pure doctrines of Christ. And yet it takes a hundred and seventy years from the death of Christ, and a hundred from the last of His personal disciples, to establish this abomination as a part of the Christian creed.

What Scripture proof can you give for the inspiration of the Bible ?

Nay, this is granting more than the facts will warrant, for it cannot be said to have been established as an article of belief at this period, but only that it was received by some Christians. Others did not receive it at all; and the Gospel doctrine of universal restoration was held by some of the most eminent of the Christian fathers at the same time Tertullian and others avowed their faith in endless punishment.

This doctrine, like every other, is based on Scripture, and is not an invention of man.

Warburton, and also Whateley, quoted below, take ground that the doctrine of a future existence is not recognized in the Old Testament. In this they are wrong, as we have attempted to show in the fifth section of this chapter.

In opposition to Rome they further defended the clearness of the Bible.

As yet, then, we have no revelation of the doctrine in review, but only the infliction of the temporal punishments of the Law. But one more example, of another sort.

The Origin and History of the Doctrine of Endless …

Expressly means clearly. To depart means to apostatize. Apostasy is the deliberate and permanent rejection of Christianity after a previous profession of faith in it. Doctrines of devils or doctrines that are taught by demons. An apostate is not someone who never knew the truth but someone who knew it and rejected it. He may have even been involved in various religious activities. But because he never truly knew God, he was lured away by the siren voices of the demons behind idols and false religious systems.

So far, then, the Law itself in its statement of penalties, the history of the nation of the Jews, and of the most remarkable cases of crime under the Law, preserve a profound silence on the subject in hand. Not a word, not the most obscure allusion to the doctrine of unending punishment, is to be met with in any of the divine records of transgressions or judgments.
