There are two ways to interpret scripture: a carnal way and a spiritual way. The carnal way would ascribe our own works to this saying of Jesus. If only we would have the same commitment as Jesus then we could accomplish great things for GOD, as he did. Yet on the cross, our feet and hands are bound and nailed. We are helpless and can do no good works for GOD, through our own power, in that position. So what is the true meaning of this scripture?
It is useful to think of the full gospel in four areas: forgiveness of sin, deliverance from sin on this earth, divine health, and prosperity. It is simple to show that the gospel includes these areas because Jesus manifested all four of them on the earth: he was in right standing with GOD, he lived a sinless life on this earth and he walked in divine health and prosperity. If Jesus lived that way then we should also walk in the same way here on the earth (1 John 4:17). If we miss the mark, or the standard of Christ, then this is what the Bible calls sin. We are falling short of GOD's will for our life.
Saving faith requires hearing, both in the ear and in the heart. Hearing in the ear represents physical hearing and hearing in the heart represents spiritual hearing. Hearing in the ear is essential, as it is providing GOD with something to quicken. This is why step A (Acknowledge) is so important, but this is only the beginning of the process. GOD must then quicken the knowledge in the head so that it becomes spiritual hearing or Rhema, discussed in the passage above.
