Understanding Is Discerned Spiritually. Understanding is achieved by accessing the heart. That is a spiritual application, and the scriptures emphasize repeatedly the necessity to apply the heart in understanding. (Proverbs 2:1-10) This simply means to apply our spiritual senses instead of our physical senses.
Explanation: Everyone has a spirit, and a body. We live in a physical world where our physical senses are spontaneously exercised daily. The spiritual realm is just as real as the physical, and is all around us. Since our physical side naturally dominates, our spiritual side is pushed to the "back burner" because of the constant priorities naturally given to the physical. Our first and strongest input is received through our physical sensory system. The spirit acts as an interface when we learn to listen to it. Some call it a conscience, and that probably best describes it. When followed it yields a warm or peaceful feeling to the heart. When ignored it gets pushed off the burner altogether and becomes cold. (See Matt; 24: 12)
When consistently ignored the individual becomes callused, or "past feeling" (Eph. 4:19). Free choice is a test of true character and the choice is ours as to which "impulse" we act on, spiritual or physical. (Josh. 24: 15) When we learn to give priority to our spirit self, then we can dominate the physical self. Our own spirit can have power over the actions of the physical, through the exercise of choice. The spirit then is placed on the "front burner," and the physical is put on the "back burner," ready for appropriate use to enhance our spiritual life. (The focus of most is to enhance their physical life.)
Perhaps the most profound definition of slavery is one who is ruled by his passions. On this theme Jesus proclaimed " . . . the truth shall make you free." Understanding by spiritual discernment is achieved through faith, by acting on feelings of some purpose that the physical senses do not always understand, and probably protest. Sacrifice and even denial are key essentials to higher understanding.
This is the process by divine design that develops Christ-like love, as we follow Jesus in His example of the same.
Understanding Grows With Love.
Jesus said: "If you love me, keep my commandments." A genuine love of Christ is the only source of strength that will enable one to overcome all evil. Consider the strong urge by any individual to do any wrong. A thief, for example, can postpone his deed when he sees the risk of being caught. The fear of punishment is the motivating force that provides the ability to temporarily curb the action. He made the right choice, but not for the best reason. The important factor here is that the ability to control behavior was proven. It was temporary because the next opportunity, where being caught is not a risk, he will succumb.
God also, presents punishment for our misdeeds, but if that is all which motivates us, we too will eventually succumb to temptations. But what if the motivation to choose the right was generated by honor, respect and love for the Savior instead of a fear of punishment? Love is an eternal principle, and thus with love, instead of fear as the motivation to exercise one's ability to control behavior, self-control would also be eternal. (Is this not the infrastructure of a Heavenly society?)
When we sin, our love for Jesus is obviously not our greatest motivation. When we sin, it is a simple indicator that our love is not yet up to our potential. We do not even yet understand the beginnings of our own potential, until we learn to apply this level of love. The essence of true Christianity is to love God with all our hearts, might, minds and strength.
