As it is in the natural so it is in the spiritual as God created all things. Jesus uses His creation to reveal a deep spiritual truth to His disciples. That is how to bear fruit, how to love one another and how to be a disciple.
One day a young pastor said to me, ‘everyone tells me I must love. I must love God and I must love others, but no one can tell me how can I love. Please tell me how can I love?’ Jesus reveals to us the secret of success. That is how to bear fruit, how to love and how to be a disciple.
