Of course, the final test will occur when mankind appears before God at the time of the final judgment. In complete fearlessness he says:
“And I exhort you to remember these things; for the time speedily cometh that ye shall know that I lie not, for ye shall see me at the bar of God; and the Lord God will say unto you: Did I not declare my words unto you, which were written by this man, like as one crying from the dead, yea, even as one speaking out of the dust? I declare these things unto the fulfilling of the prophecies. And behold, they shall proceed forth out of the mouth of the everlasting God; and his word shall hiss forth from generation to generation. And God shall show unto you, that that which I have written is true.”
