Understanding is not knowledge. It is "a spiritual birth, a revelation of God within the heart of man." Understanding is the awareness of your oneness with God, that God is not just the giver of gifts, God is the gift. This understanding does not come from the world. Oh, we can read and study all the knowledge available to us, and it may lead us in the right direction. However, we will never reach the destination until we find the kingdom of heaven within ourselves. Not until we recognize the power we have over sickness, sorrow, and even death itself. Not until we recognize the presence of God within us, that God acts through us as us.
The spiritual consciousness of God within as wisdom, life, power can only inhabit a person who sees God as being all that is, who lives in the here and now, and most important, who possesses a desire for spiritual understanding that is greater than riches, honor, power, and selfish glory.
Spiritual understanding takes time. You have been living in the external world for a long time. Begin your journey by knowing that you are not separate from God. Take small steps to begin to deny envy, jealousy, anger, sickness, and all imperfection and to affirm love, peace, and health.
Do not ignore the questions that arise, but with effort, affirm the words of Truth that you have learned. One day without warning, these words will enlighten your heart. "The old things are passed away, behold, they are become new." [II Cor. 5:17] With spiritual understanding, you will have new ears to hear and eyes to see. Your teacher will not be out there; your new teacher will now reside in you as your indwelling Christ.
However, spiritual seeking is not the goal. Spiritual understanding requires that there be an inlet and an outlet because it is the nature of things. As Cady said, "We grow by using for others the light and knowledge we have. We expand, as we go on step by step in spiritual insight, until in the fullness of time—which means when we have grown spiritually up to the place where God sees that we are able to bear the many things—we receive the desire of our hearts, understanding."
