The only time Jesus talks about future time is when he tells us not to worry about it (see Matthew 6:25-34). Don’t worry about times and seasons, don’t worry about when God will return, don’t worry about tomorrow.
Thinking about the future keeps us in our heads, far from presence. Jesus talks about the past in terms of forgiving it. Some say forgiveness is central to his whole message. Jesus tells us to hand the past over to the mercy and action of God. We do not need to keep replaying the past, atoning for it, or agonizing about it.
.. Yet, as practitioners of meditation have discovered, the mind can only do two things: replay the past and plan or worry about the future. The mind is always bored in the present. So it must be trained to stop running backward and forward. This is the role of contemplation.
