ANSWER: The fact that they are not found in the Bible does not disprove the doctrine any more that the absence from the Revised New Testament of Trinity, incarnation, atonement, omniscience and omnipresence disproves these fundamental truth which are abundantly taught in other terms. The resurrection of both the just and the unjust, the General Judgement of the whole race resulting in its everlasting awards, as in Matthew 25:46, and other texts, are sufficient proof that man has an immortal soul. This doctrine, like the existence of God, is not proved in the Bible, but always assumed as an intuitive truth universally believed. Such a truth is always weakened by attempts to prove it.
