We only need to do what God puts on our hearts to do, and doubting His ability to work beyond us is not the best way to hear Him. The great lie of this broken universe is that God cannot be trusted and that we have to take care of ourselves. That's the lie that snagged Eve. The serpent convinced her that because God has ulterior motives, she couldn't trust what He said. By not trusting Him she did what she thought best for herself. But it backfired, didn't it? It always does... Our moments result from grabbing for ourselves that which Father has not given us.
We are to live on His ability, not our own.
That was taken from the book So You Don't Want To Go To Church Anymore by Wayne Jacobsen and Dave Coleman on page 107. Don't let the name of the book fool you. I would say anyone should read this book because the main point is that our focus should be on having a relationship with Jesus before anyone, anything or any institution. That's a good reminder whether you want to go to church or not. :)
