If we focus on the past or the future, we lose our present.
I think it was very smart of God to not give man the past or future. I believe God knew we could only handle the present. The problem is that man often decides to ignore the daily moments and waste time worrying about the future or become frozen in the past. When this happens, we miss life.
To live in the fullness of time and to be most alive, we need to become awake to all our precious moments in life and see Jesus in all of them.
“This is the day the Lord has made; let us rejoice and be glad in it.”
