Your absolutely right and there’s nothing wrong with going to a Rebba or a kever for a Bracha but you going directly to the ruler Hashem for help in your time of need is way more powerful then going through a middleman or messenger.
Hashem loves hes special chosen nation klal yisroel and ia waiting at anytime to help anyone out in their time of need. The person just has to call out wholeheartedly directly to Hashem and then watch how fast his prayers are answered.
All of us have heard, read & seen tons of true stories of people who had their first child at 42 or had a sick child in critical condition, & then the doctor says i’m very sorry but your daughter has only 3 hours to live & then he comes back 2 hours later & says its really a miracle but your child is beginning to recover etc…. Why is it that they finally had a child & the child recovered? There could be tons of answers, but the most common answer Is a Pasuk we say 3 times a day in Davening. Hashem is close to all who call to him, to all who call out truthfully. (Tehillim 145)Because they cried out from their heart, they really meant what they were saying when they davened to H-shem to have a baby or for his daughter to recover etc…. there’s a reason we call Hashem, Avinu She’bashamayim (our father in heaven) Hashem loves us from a father to a son & is waiting to put his Shchina (presence) & his bais hamikdosh back in this world. If we really cried out for the Bais Hamikdosh from our heart with truth & show that we are missing it, then we wouldn’t still be in Golus today.
