"The vigor and power and comfort of our spiritual life depends on our mortification of deeds of the flesh"

This quote by John Owen speaks to the significance of self-discipline and restraint in order to lead a spiritually fulfilling life. By "mortification of deeds of the flesh", Owen is describing the practice of avoiding worldly desires and temptations. He is suggesting that by denying ourselves of these satisfaction, we can instead concentrate on our spiritual development and advancement. This can result in a greater sense of vigor, power, and comfort in our spiritual life. In other words, by denying ourselves of the important things that can sidetrack us from our spiritual journey, we can instead concentrate on our spiritual development and advancement. This can result in a greater sense of purpose and fulfillment in our lives. By practicing self-control and restraint, we can end up being more in tune with our spiritual selves and find a higher sense of peace and satisfaction.
