By "the present truth" Peter means the truth which is present with the believers and which they have already received and now possess.

彼得所说“现有的真理”，意思就是信徒所已经接受，并现在持有的真理。在本章第一段，（3～11，）彼得用那为着正当基督徒生活之神圣生命的供备，豫防背道的事。在第二段，（12～21，）他用神圣真理的启示，作第二种抗毒剂，以豫防背道中与今天摩登派的学说相似的异端。对背道的事，彼得所用的抗毒剂，乃是生命的供备和真理的启示。

在十三至十四节彼得说，“我认为趁我还在这帐幕的时候，以题醒激发你们，是正当的，知道我脱去这帐幕的时候快到了，正如我们主耶稣基督所指示我的。”“帐幕”这辞指暂时的身体。（林后五1。）脱去帐幕，即脱去身体，脱下身体，（4，）离开身体，肉身死亡。彼得和保罗一样，（提后四6，）知道他要殉道离世，并且他现在已经豫备好了。他记得主吩咐他要餧养主的羊时，对他说到他死的事。（约二一15～19。）

在彼后一章十五节彼得继续说，“不仅如此，我也要竭力，使你们在我去世以后，时常记念这些事。”去世，或，离开；（原文与路加九章三十一节者同；）彼得的意思即离世。“这些事”，再次指彼得在彼后一章一至十一节说过的事。

By "the present truth" Peter means the truth which is present with the believers and which they have already received and now possess. In the first section of this chapter (vv. 1-11), Peter uses the provision of the divine life for the proper Christian life to inoculate against apostasy. In the second section (vv. 12-21), he uses the revelation of the divine truth, as the second antidote, to inoculate against the heresy in the apostasy, a heresy similar to today's Modernism. 

In verses 13 and 14 Peter says, "And I count it right, as long as I am in this tabernacle, to stir you up by a reminder, knowing that the putting off of my tabernacle is imminent, even as also our Lord Jesus Christ made clear to me." The word "tabernacle" refers to the temporal body (2 Cor. 5:1). To put off the tabernacle is to put off the body, to be unclothed of the body (2 Cor. 5:4), to leave the body, to die physically. Peter, like Paul (2 Tim. 4:6), knew that he would leave the world by martyrdom, and he was ready for this. He remembered the Lord's word to him concerning his death, when He charged him to feed His sheep (John 21:15-19). 

In verse 15 Peter continues, "And I will also be diligent, that after my exodus you may be able to have these things always in remembrance." By "exodus" or departure (the same Greek word is used in Luke 9:31), Peter means to leave the world. Once again, "these things" refer to what Peter has covered in 1:1-11.
