The hypocrites are wavering because they follow their desires, when they find a powerful side, they incline to it, then when they find wealth with another side, they incline to it. So they neither belong to believers neither to disbelievers.

( وَمَن يُضْلِلِ اللَّهُ فَلَن تَجِدَ لَهُ سَبِيلًا … ) (…And whoever Allah leaves astray – never will you find for him a way): Allah (swt) guided them but they chose the blindness over guidance:

 إِنَّا هَدَيْنَاهُ السَّبِيلَ إِمَّا شَاكِرًا وَإِمَّا كَفُورًا

(Indeed, We guided him to the way, be he grateful or be he ungrateful.) (Al-Insan: 7)

Allah (swt) showed us the path of guidance and guided us to it. When we choose it, He (swt) helps us to follow it, but when we chose the bad way, then Allah (swt) will leaves us astray.
