Those in the so-called telestial kingdom are resurrected but don't have exaltation which is eternal life according to Mormonism.
And? The scriptures testify all men will not enter into eternal life, but all men will be resurrected and judged according to works, and that for life or damnation:
John 5:28-29---King James Version
28 Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice,
29 And shall come forth;
they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
"We believe that through the Atonement of Christ, all mankind may be saved, by obedience to the laws and ordinances of the Gospel."
“Those who gain exaltation in the celestial kingdom are those who are members of the Church of the Firstborn; in other words, those who keep all the commandments of the Lord. …
How is that any different from the Savior's testimony here?
Matthew 19:16-19---King James Version
16 And, behold, one came and said unto him, Good Master,
what good thing shall I do, that I may have eternal life?
17 And he said unto him, Why callest thou me good? there is none good but one, that is, God
: but if thou wilt enter into life, keep the commandments.
18 He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness,
19 Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.
Certain apostates have taken this sacred name upon themselves, blasphemously claiming to have met all of these requirements, when they are in fact in a state of wickedness and rebellion.

Could you explain how that is any different than this testimony?
2 Peter 2:20-22---King James Version
20 For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome,
the latter end is worse with them than the beginning.
21 For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.
22 But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.
