D&C 76

Paul taught - 

"The Spirit itself beareth witness with our spirit, that we are the children of God:

17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together."   (Romans 8:16–17)

The Prophet Joseph Smith saw of those that receive exaltation - 

"They who dwell in his presence are the church of the Firstborn; and they see as they are seen, and know as they are known, having received of his fulness and of his grace;

95 And he makes them equal in power, and in might, and in dominion."  (Doctrine and Covenants 76:94–95)

What a great gift and promise!

With this great vision we are also told - 

"This is the end of the vision which we saw, which we were commanded to write while we were yet in the Spirit.

114 But great and marvelous are the works of the Lord, and the mysteries of his kingdom which he showed unto us, which surpass all understanding in glory, and in might, and in dominion;

115 Which he commanded us we should not write while we were yet in the Spirit, and are not lawful for man to utter;

116 Neither is man capable to make them known, for they are only to be seen and understood by the power of the Holy Spirit, which God bestows on those who love him, and purify themselves before him;

117 To whom he grants this privilege of seeing and knowing for themselves..."  (Doctrine and Covenants 76:113–117)
