Sometimes looking at the current happenings, the thought crosses my mind "I wish I could go back in time and ask Jesus and/or the apostles for advice in person".
Then I catch myself and remember that my faith is based on Jesus being resurrected and being present NOW through the Holy Spirit, I shouldn't need to go back in time to ask and receive advice from Him.
