After Obi-Wan’s death, he becomes one with the Force, able to coach Luke through his mission. With his master’s help, Luke remembers his training and uses the Force to deliver the killing blow to theGalactic Empire’s ultimate weapon. Obi-Wan’s mentorship was instrumental in Luke’s training, but when Luke was at his most vulnerable, Obi-Wan insisted that Luke had to fight Darth Vader on his own.
When Luke chooses to leave his training with Yoda to rescue Leia and Han from Vader, he is encouraged by both Yoda and theForce ghostof Obi-Wan to stay and train. The Jedi Masters knew that despite his new skills, he wasn’t yet ready to take on the Sith Lord on his own.

He Was His Father’s Counterpart
Yoda and Obi-Wan were both well aware of Luke’s true relationship to the Sith Lord and this changed the way they believed the fight between them should go down. They knew he was too powerful for Luke to completely defeat on his own, yet they still believed it was something he needed to do by himself. Having witnessedAnakin’s fall to the dark side, they knew that Vader’s son would carry some weight in the Force. Luke and Vader represented two very different sides of the Force that needed reckoning.

Anakin’s significance to the Jedi was clarified in the prequel trilogy.He was believed to be the subject of a prophecy that foretold he would bring balance to the Force. Though the true meaning of this Jedi prophecy was unclear, Anakin’s time as a Jedi certainly didn’t bring balance.

Obi-Wan Didn’t Want To Intervene In The Supposed Will Of The Force
You Can’t Fight Fate
The belief that it was meant to be Luke who brought Vader down kept Obi-Wan from interfering. Obi-Wan had spent the better part of his exile on Tatooine meditating and reconnecting with the Force. He understood that things happened for a reason and that it can be dangerous to meddle with the will of the Force. After all, trying to outsmart the future is what spiraled Anakin down the path to the dark side, and Obi-Wan wasn’t about to make the same mistake. He simply did what he could to prepare Luke for what he believed was inevitable.
Obi-Wan had already dueled Vader three times by this point, andObi-Wan had come to terms with the idea that he wasn’t going to be able to defeat or redeem his former apprentice. As Luke’s skills grew, things seemed to become clear to Obi-Wan. Anakin’s pure-hearted son would be the perfect counter for the Sith Lord that had devoured Obi-Wan’s friend - and Obi-Wan was right, from a certain point of view. The Force had other plans for Darth Vader, though Luke was in fact instrumental in Vader’s destruction.
