Before I became completely aware of what was taking place in my back yard - I was in prayer. Prayer for family and friends in my life - I do that as I dry my hair in the morning (you should try it, it is a great time to spend with God and also explains why my hair either looks really good or doesn't look too great).
Back to my point...when I realized the sound and what was taking place - it hit me. I was praying that the lives I was lifting to God would be cleared of the situations or circumstances that were hurting or causing them pain. That God would move in their lives toward healing or discernment.
The sound of the pump truck made me wish I could just have a truck pull into my heart or life and start cleaning out the "eck" that can fill it some times. The people I care about could just call "Pump It" and have their lives cleared of the pain and hurt that can fill their days.
That became my prayer.
So in case you don't think you can pray because you don't know what to pray for...
