By this My Father is glorified, that you bear much fruit; so you will be My disciples. John 15:8 (NKJV)
I honestly believe that a farmer’s greatest joy is when harvest time comes, and he sees that his trees or seeds have produced much fruit or crop in that year. So much so that farmers will define a year better than the last based on more fruit produced. I can only imagine the joy, delight and gladness our Heavenly Father gets when he looks upon His children and see them producing much fruit every year and year after year.
