Prayer is never an acceptable substitute for obedience. The sovereign Lord accepts no offering from His creatures that is not accompanied by obedience. To pray for revival while ignoring or actually flouting the plain precept laid down in the Scriptures is to waste a lot of words and get nothing for our trouble.
On this National Day of Prayer and Remembrance, we ask almighty God to watch over our nation, and grant us patience and resolve in all that is to come. We pray that He will comfort and console those who now walk in sorrow. We thank Him for each life we now must mourn, and the promise of a life to come.
I do know this: God does answer your prayers, but it's not always in the way you expect. God knows what's best for us, though, so there's no need to worry when things don't go how we originally wanted them to go.
If by prayer
Incessant I could hope to change the will
Of him who all things can, I would not cease
To weary him with my assiduous cries;
But prayer against his absolute decree
No more avails than breath against the wind
Blown stifling back on him that breathes it forth:
Therefore to his great bidding I submit.
