Jeremiah 17 - its meaning then and now

Thus says the Lord:
“Cursed is the man who trusts in man
And makes flesh his strength,
Whose heart departs from the Lord.
For he shall be like a shrub in the desert,
And shall not see when good comes,
But shall inhabit the parched places in the wilderness,
In a salt land which is not inhabited. Jeremiah 17.5-6
