Jesus proclaimed that God’s realm truly exists above our evil world. We are all from below from clay, full of bitter thoughts. The devil’s seed bring forth rotten fruit. The natural man cannot realize God’s realm, but may feel dimly its existence.
Christ is not of our world; His soul proceeds from the Father. He placed his Father’s realm on high but not in a geographical sense. As gravity is lowered the higher we go, so also the nightmare of sin vanishes as we come nearer to God. Our world is a prison from which we cannot escape. We are the offspring of our environment refusing to submit to God’s love. Our lives are full of sin. At this point Jesus used "sins" in the plural, since from our opposition to God many sins and errors arise. We are like the leper full of sores and scars. Just as that wretch dies slowly, even though he is still alive. Similarly sin destroys man. We shall die because we have sinned. What is sin? It is unbelief, for he who is bound to Christ lives for ever – the blood of God’s Son keeps cleansing us from sin. His power cleanses our consciences and sanctifies our thoughts. But whoever stays apart from Christ, chooses death, remaining in the prison of sins, awaiting judgment. Faith in Christ alone frees us from God’s wrath.
Who then is Jesus who requires faith in his person? Again he describes himself "I am He" (John 6:20 and 8:24). Thus he summarizes all the great testimonies of himself. He called himself the Lord of truth, the living God, the Holy One who revealed Himself to Moses in the bush with the same phrase "I am" (Exodus 3:14; Isaiah 43:1-12). In no other is salvation. Every Jew knew these two phrases, but dared not pronounce them, to avoid using God’s name in vain. But Jesus called himself by them publicly. He is not just Christ the Son of God, but also Yahweh, God in truth.
He is the epitome of the Gospel. Christ is God in the flesh. Whoever believes in him lives. But he who rejects him and objects to his authority deprives himself of forgiveness. Faith or unbelief decides man’s destiny.
