EPA in Numbers 9-10

I read Raymond Brown's book on Numbers of the BST series this morning.
I happened to find his exposition of ch 9-10 with the title of Three Dimensional Grace.

What he emphasized as the key words shown are Encouragement(E)from the past,Priorities (P)in the present and Assurances(A)for the future.

This is not Economics and Public Affairs (EPA) as we learnt in High school years BUT God's abundant provisons for His chosen people in the past as well as in we Churches these days.

Do we have encouragements in our past walk with the Spirit,
Experiencing His disciplined prirorities in our daily lives now and have
Loving assurances from our Heavenly Father as we face up tomorrow ?

It's really important to have these EPAs to be our new perspective.
