Why did we ever get the impression God stopped communicating when the Bible was compiled? Why did we jump to the conclusion that revelation had ceased when Revelation was penned?
The language of heaven is apparent when you simply look up: "The heavens declare the glory of God; the skies proclaim the work of His hands. Day after day they pour forth speech; night after night they display knowledge" (Psalm 19.1-2).
Do you notice how often the sky is used in Scripture as revelation of God? In one regard, God through His prophets speaks to those who worship the stars; who look to the heavens as a map for life. Throughout the prophets, those who worship the creation and fail to see the revelation of the Creator are condemned for their misplaced spirituality. Yet, God Himself was not above using the celestial bodies to communicate.
Remember how he got the attention of the Magi at the birth of Jesus (see Matthew 2.1-12)? Most scholars believe the Magi were considered "wise men" because of their schooling in and understanding of astrology. The bright star in the east was simply God's way to get their attention, to communicate in their language as a mechanism to lead them to His Son.
When David looked to the heavens, he heard God. When the Magi looked to the heavens, they heard God. What do you hear when you look to the heavens?
