Therefore my heart is glad
and my whole being rejoices;
my body also rests securely.
For you will not abandon me to Sheol;
you will not allow your faithful one to see decay.
You reveal the path of life to me;
in your presence is abundant joy;
at your right hand are eternal pleasures.
We have already seen allusions to the death of the Messiah in the Old Testament, and even His resurrection. Here in this psalm, we see them again. This verse shows us that even though the Messiah will die, God will not abandon Him to death. The corruption and decay that comes to the body after death would not touch the body of the Messiah. We see the promise that He would be raised before His body would decay.
This was Jesus. God spared His Messiah from corruption. He raised Him from death in three days. Far more than just being spared from corruption, the body of Jesus was glorified. His body was made fit for eternal residence in Heaven. Likewise, in our death, we can be certain that a glorified body awaits us. We have hope that we will not be abandoned in death, but will be raised up and protected from eternal corruption.
