Today you can be anywhere in the world and send or receive messages digitally via email. Sending email has eclipsed traditional mail for years now. Sending knee-mail is similar (you can be anywhere)—but with better results! You don't need wifi or a modem; you don't need an electronic device or a computer. Before Jesus left His disciples, He wanted them to get "online" with the Father and stay connected through the simple yet powerful means of prayer.
