Story: Perhaps I can explain it better by telling you as story that the famous Canadian 20th Century Pentecostal missionary, Jonathan Goforth, used to tell.
When Jonathan was 16 and still living at home with his parents, his father bought a second farm. He asked Jonathan to look after a huge field on that farm and get it ready for harvest.
Jonathan loved his father and wanted to please him. So he ploughed and weeded the field. He tilled it, bought the best grain and planted it in the field.
When the field was ready for harvest, Jonathan brought his father over to inspect it.
Jonathan’s father came and stood on a small hill overlooking the field and said nothing.
He simply surveyed the field to see if he could find weeds.
When he found nothing, Jonathan’s father simply smiled.
Jonathan Goforth used to say: "It was the smile on my father’s face that was all the reward I needed. So it is with our heavenly father when we do what he commands us to do."
