"With the past, I have nothing to do; nor with the future. I live now." - Ralph Waldo Emerson
I was just thinking about this earlier today about something I had read while I was at adoration this past weekend.
Every day, every hour, every minute is the chance of a new start and beginning. God gives us the opportunity so many times in our life to try and try again. Most of us don't even think about this chance or don't even consider it thinking what we did was so bad or wrong. I believe God challenges us to take these moments and better ourselves from this previous one. It doesn't have to be anything major or mind-blowing, just little things. We can learn how to grow and be better people both inside ourselves and towards others.
It also ties into the thought of mindfulness, to live in the moment. We take every breath we are giving and just live it to the best of our ability. We do not live in the past, nor do we live in the future... we live in the now. If you focus on the past, you will be living your life in the past and forget to live in the present... same can be said about the future.
