Present Truth 2 Peter 01:12

9But he that lacketh these things is blind, and cannot see afar off, and hath forgotten that he was purged from his old sins. 10Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall: 11For so an entrance shall be ministered unto you abundantly into the everlasting kingdom of our Lord and Saviour Jesus Christ. 12Wherefore I will not be negligent to put you always in remembrance of these things, though ye know them, and be established in the present truth. 13Yea, I think it meet, as long as I am in this tabernacle, to stir you up by putting you in remembrance; 14Knowing that shortly I must put off this my tabernacle, even as our Lord Jesus Christ hath shewed me. 15Moreover I will endeavour that ye may be able after my decease to have these things always in remembrance.

The truth is only present as it is remembered.  Truth without remembrance or the instance of the initial revelation of the Holy Ghost is non existence in the realm of this world.

John 14:26
“But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.”
