We mustn’t wish time away or live in the past because God asks us to live in the present. I think that could be one of the biggest challenges of this life, though: living in the present, not worrying about tomorrow (Mt 6:34). When you head into prayer, tell God what you are afraid to give over to him. What is it that you are worried about? (Worries often are about something you project into the future.) Tell him all about your worries and let him respond. He will invite you to abandon all to him. He wants you to let him take care of everything. So, end your prayer with this abandonment prayer.
