God is all in all and there can be nothing besides Him, is a statement that many cannot understand. It was so in the days of Jesus, and is so now. On account of their spirituality, Jesus and Paul were in advance of the people. Now, as then, if we advance spiritual thought, many say they cannot understand. If we interpret the Bible spiritually, and consult the spiritual understanding which testifies of Truth, instead of the five senses which testify of material or mortal man, many passages will be plain which seem to be obscure. It requires the enlightenment of Spirit to understand Spirit. We cannot understand it from a material lookout. Christ's kingdom is not of this world—it is spiritual. God is Spirit, and we are to worship Him in Spirit and in Truth. We are spiritual, and our worship must be the same. We must get upon a higher plane, and discern things in their proper sphere and light; then we shall discern the Christ Principle and see beauty and grandeur in the spiritual worship of God.
A few thoughts from such an interpretation: Christ is the Life, the Truth, and the way. We are in sympathy with Him because we are His. He also said He was the resurrection. His resurrection was also the Apostles' resurrection which also helped them in raising others to Life in Him. We are resurrected through Him to consciousness of the death of the carnal man; from dead works to spiritual Life which is the only Life.
Wherefore saith the Spirit, "Awake thou that sleepeth and arise from the dead and Christ shall give thee light."
