The ideas existing in the spirit are far greater than those here. Faith is the process by which these things come forth into existence here:
`And now, I, Moroni, would speak somewhat concerning these things; I would show unto the world that faith is things which are hoped for and not seen; wherefore, dispute not because ye see not, for ye receive no witness until after the trial of your faith. (Ether 12:6)`
It is only through faith that they can come into being:
`For behold, I am God; and I am a God of miracles; and I will show unto the world that I am the same yesterday, today, and forever; and I work not among the children of men save it be according to their faith. (2 Nephi 27:23)`
You exercise deep faith by creating outcomes here based on desires and reasons that exist only in the spirit.
Reason, desire, and action are the nexus between the spiritual and physical world. Reason and desire drive the creation of new things on earth and the reconciliation of things on earth to things in heaven.
For example, through desire, the Lord can drive us to search to fill longings that surpass those which satisfy normal people. Every person has within them a faint but pervasive memory of God—planted deep within them from their interactions with him before birth. In a way, every desire we have—no matter how base or carnal—is an attempt either to satisfy or silence that deep drive to reconnect with the divine.
Some few manage in this life to make explicit this divine longing, coming to realize what it is and that normal life cannot satisfy it. For example, Peter pointed out that, after learning from Jesus, nothing less would do:
Then Simon Peter answered him, Lord, to whom shall we go? thou hast the words of eternal life. (John 6:68)
Paul similarly remarked how learning about the Lord decreased the value of all not found in him:
Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ. (Philippians 3:8)
It is in the mind that our access to the spirit provides us greater understanding over what we observe in the physical world, as well as the physical instantiation of the limitless information we have access to in the spirit. Physical objects are limited instantiations of the infinite spirit. Physical objects provide a filter through which specific facets of the infinite are discretized and made more apparent to our limited understanding.
Reason transforms carnal experiences and observations of the real world into the space of the mind, where higher-order analysis can take place. Higher order reflections on reality include, for example, the motives, means, and feelings of sentient beings. In all things, higher order reflections include relationships between the parts of the whole and different objects. For example, higher order thought is not limited to the eye’s view of a drop of water, or to the feeling of wetness, but includes the microscopic bustle of the countless small organisms and molecules comprising the droplet yet invisible to the naked eye, as well as questions about why droplets are physically drawn to each other, or why they roll down a vertical surface in the way they do.
Reason is the link between matter and mind. Reason projects the contents of the mind into the physical world. Reason is the means through which information is channeled from the physical world into the mind, and from the mind into the physical world. This transmission happens through action.
Action is required to observe and think about the physical world. Action is required to act on information thus extracted. These actions generate further observations to provide updates to desire and reason.
So, we see that, without each component of the faith cycle, it is not possible to bridge the gap between the spiritual world and the physical world. While the Christian world continues the long-standing debate about what James meant exactly when he proclaimed “faith without works is dead” (James 2:20), we could further complicate the controversy by adding that faith without reason is dead, as is faith without desire.
