John 4:34 ‘My food,’ said Jesus, ‘is to do the will of him who sent me and to finish his work.
We enjoy eating food when we feel hungry. We enjoy drinking something if we are thirsty. By the same token we should enjoy working for God when we feel the need to do so.
Jesus was always ready and willing to go the extra mile to work for His Father and that is our example to work for God as well. He wants us to be willing workers so that others will see not just how enjoyable it can be but also how much Joy God wants to bring into our lives.
Jesus did not give up after showing He was willing but continued right up until His work was finished. We should too.
