As Jesus prepared to leave his disciples, he did his best to explain what lay ahead, and to reassure them. He also let them know that they would not be left alone:

"The Friend, the Holy Spirit whom the Father will send at my request, will make everything plain to you. He will remind you of all the things I have told you. I’m leaving you well and whole. That’s my parting gift to you. Peace. I don’t leave you the way you’re used to being left—feeling abandoned, bereft. So don’t be upset. Don’t be distraught."
