Hashem knows what’s best for us

Hashem loves us more than any father in the world now if a father knows what's best for his son he puts his son on the back because he wants his son to crawl and then eventually walk and the father knows what's best for the son does Hashem not know what's the best for us can we ask why am I suffering because Hashem says I know what's best for you these are the steps this happens and that happened in the aftermath finally you say oh oh now I got it oh Hashem thank you so much for the suffering
