If you’ve ever read Matthew 7:7, you’ve likely noticed that all three promises imply us DOING something first. When I was a life insurance agent I knocked on many many doors to try to round up new clients. Most didn’t even bother opening the door. A lot of the ones who did open were not interested. Every once in a while, I came across a perfect opportunity.
I think God wants to know that we will be persistent. Just because the door isn’t opening doesn’t mean you should stop knocking. You may not be standing at the right door just yet but at least you’re in the building!
