In this sermon, I wrap it up with the fact that to survive in the physical/natural world your 5 senses and your million other sensory receptors are essential. However in the spiritual world faith is the currency.
In order for your joy to increase your faith in God must increase. You must learn gradually to remember that your senses are limited to the physical and then learn to stay out of the way for your faith in God to be activated.
Listen and be blessed.
