May 29 Forget 

Regret nothing. Not even the sins and failures.  When a man views earth’s wonders from some mountain height he does not spend his time in dwelling on the stones and stumbles, the faints and failures, that marked his upward path.

So with you.  Breathe in the rich blessings of each new day – forget all that lies behind you.

Man is so made that he can carry the weight of twenty-four hours, no more.  Directly he weighs down with the years behind, and the days ahead, his back breaks.  I have promised to help you with the burden of today only, the past I have taken from you and if you, foolish hearts, choose to gather again that burden and bear it, then, indeed, you mock Me to expect Me to share it.

For weal or woe each day is ended.  What remains to be lived, the coming twenty-four hours, you must face as you awake.

A man on a march on earth carries only what he needs for that march.  Would you pity him if you saw him bearing too the overwhelming weight of the worn-out shoes and uniforms of past marches and years?  And yet, in the mental and spiritual life, man does these things.  Small wonder My poor world is heartsick and weary.

Not so must you act.

This one thing I do, forgetting those things which are behind … 
I press toward the mark for the prize of the high calling of 
God in Christ Jesus.  Philippians 3:13,14
