Here's one possible explanation.
excerpt from Yaarot Devash 1:1 on his explanation of the Amidah
Accepting the repentance of a sinner is in the category of
'resurrection of the dead', because 'a wicked person, even when alive
is called dead'. And when he repents, this is like a resurrection from
Therefore, one should pray that HKBH should revive him and accept his
prayer. And when a person sins, his soul leaves him, and he should
pray that HKBH revives him with the 'dew of ressurection'. Because the
(physical) 'dew', HKBH sends without our initiative (hitorerut letata)
(unlike rain which needs prayer). So too, we recall the dew to bring
down and revive us with His holy blessing (shefa).
Therefore in this beracha, one's intent should be to revive in this
world and in the time of the resurrection of the dead. And this will
fix in one's heart complete faith in the future ressurection because
'the word of G-d does not return empty', which he promised to us to
awaken us from our graves and then the world will be rectified
completely. And this brings one to believe in the creation ex-nihilo
(something from nothing), which is similar to the revival of the dead.
And in the beginning, G-d's thought was to make man head of all
creation. But with the sin (of Adam), it says 'you will surely die',
and he fell from his lofty level. But the 'thought of G-d will forever
endure'. Therefore, in the resurrection of the dead, man will return
to his level and will be head to all the angels on high, as it is
written "at that time, they (the angels) will say to Yaakov and to
Yisrael, what did G-d do". And for this every man should look forward
to with complete joy, this perfection, and he should fix himself now
as much as he can so that he will be worthy of this.
