John 7:33 Jesus then said, “I will be with you a little while longer, and then I am going to him who sent me.”

Things would be different for the disciples after Jesus returned to the Father, and he needed to warn them ahead of time. Later, after he had been raised from the dead, he told them that he would be with them always, to the end of the age. He is with us and he is with the Father, and the Spirit keeps us all One.
