Forget the former things;
do not dwell on the past.
See, I am doing a new thing!
Now it springs up; do you not perceive it?
I am making a way in the wilderness
and streams in the wasteland.
The wild animals honor me,
the jackals and the owls,
because I provide water in the wilderness
and streams in the wasteland,
to give drink to my people, my chosen,
the people I formed for myself
that they may proclaim my praise. Isaiah 43:18-21
The “past” sets the stage for the present. It is the launching point for today.
Having perspective on “what has been” is a matter of life or death – of joy or continued sorrow – of eternal significance or of no significance.
Our pain of yesterday – is just that – past pain. It is not present pain unless we choose to continue it in this day. It takes a reordering of our mind to choose God and His righteousness in this day.
Use the past to remember how to live in today.
Those earlier ones never did get to the place of rest because they were disobedient. God keeps renewing the promise and setting the date as today, just as he did in David’s psalm, centuries later than the original invitation:
Today, please listen,
don’t turn a deaf ear . . .
And so this is still a live promise. It wasn’t canceled at the time of Joshua; otherwise, God wouldn’t keep renewing the appointment for “today.” The promise of “arrival” and “rest” is still there for God’s people. God himself is at rest. And at the end of the journey we’ll surely rest with God. So let’s keep at it and eventually arrive at the place of rest, not drop out through some sort of disobedience. Hebrews 4:5-11 The Message
Our goal for “today” is to bring glory to God in each moment by living obediently as Jesus teaches us – in peace with others, acting in a righteous manner (being honest, kind, merciful, humble, meek, pure in heart) and praising God in word and deed.
So, in this day. . . Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light.” Matthew 11:28-32
Remember, “today” has enough worries of its own – so don’t dwell on what is to come.
“And why do you worry about clothes? See how the flowers of the field grow. They do not labor or spin. Yet I tell you that not even Solomon in all his splendor was dressed like one of these. If that is how God clothes the grass of the field, which is here today and tomorrow is thrown into the fire, will he not much more clothe you—you of little faith? So do not worry, saying, ‘What shall we eat?’ or ‘What shall we drink?’ or ‘What shall we wear?’ For the pagans run after all these things, and your heavenly Father knows that you need them. But seek first his kingdom and his righteousness, and all these things will be given to you as well. Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own. Matthew 6:28-34
The purpose of “tomorrow” is to live righteously today. Concentrate on today and tomorrow will take care of itself. Eternity meets us in today and will meet us again, tomorrow, either here or in Heaven.
Remember, today is tomorrow’s past so live “right” today and launch into tomorrow at the right place.
