This is from Steve Furtick's blog...I found myself saying this statement too often to my son as well...and in regards to my relationship with God, see below for my added statements...

Not Right Now

I realized the other day that I use this line on my son a little too often.
“Daddy, can we please go play on my pirate ship?”
“Not right now…”
“Daddy, can I have some juice please?”
“Not right now…”
“Daddy, will you read this book to me?”
“Not right now…”

Now it’s not that I think I should jump every time my kid says jump…or oblige his every whim.
But I miss a lot of opportunities for good interaction because of my procrastination. Because “I’ll get to it later”. And usually, later never comes.

Of course, this same scenario plays out in my relationship with God. And yours.

Speak a word of encouragement to your kids…
Not right now…
Turn off the TV and spend some time in the Word…
Not right now…
Tell somebody what you’re struggling with so you can get some help…
Not right now…

It may be trite but it’s true:
Delayed obedience is disobedience.
And most of our regrets won’t be about the things we did…
But the things we didn’t do.

My statements...

Daddy can my friend come over to play? Not right now

Daddy can you take me to the park? Not right now

Daddy can we go get a comic book? Not right now

Spend some time riding bikes with your family...Not right now

Get up an hour earlier to bring your family's

needs before Jesus...Not right now

Spend time with students who need an adult to say "I Care About You", and not just use words...Not right now

What would you do or have you not done and said, "Not Right Now"?
