‘Therefore the Lord himself shall give you a sign; Behold, a virgin shall conceive, and bear a son, and shall call his name Immanuel.’ (Isaiah 7:14 KJV)
God is a Spirit; as such He does not have a physical 3-D body as (we) Humans. And the truth is that God does not need a physical body. According to the Scriptures, “There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another” (1 Cor. 15:40 KJV). The nature and terrain of Man’s existence is localized on the Earth as such a terrestrial clothing (body) is both fitting and required.
Since, the extrinsic nature of God and Man are essential different, communication and communication model/method are both straining and challenging; but the reality is that they need and must communicate. The Bible in this respect says, “For God speaketh once, yea twice, yet man perceiveth it not. In a dream, in a vision of the night, when deep sleep falleth upon men, in slumberings upon the bed” (Job 33:14-15 KJV). To reach or communicate with Man, God uses various methods to reach or communicate with Man, this include signs.
Jesus said, “And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover. (Mark 16:17-18 KJV).
Beloved, we must give attention to signs as we give to all communication methods/models God uses to communicate with us. Signs are affirmation and attestation of God’s interest and commitments. Take good notice.
