"We saw His star in the east and have come to worship him." (Matt 2:2). This is what the Magi or "Wisemen" from the east said as they were led be a star to visit the Christ child. This is an incredible piece of the Christmas story. These men were led by God using a star to guide them as astronomers might. God uses His creation to guide us. The Holy Spirit reveals his will for us through prayer, His Word, other godly people and circumstances, then and now. I have spoken on how the Holy Spirit enveloped me and spoke to me in love and guidance through His Word. God uses stars for symbolism. In Numbers 24:17 the prophet Balaam speaks of a star coming out of Jacob or Israel to reign, speaking of David and eventually the Messiah. This star comes to earth at Christmas in Jesus birth and is proclaimed by the Lord Himself in Rev 22:16 saying, "I am the Root and the Offspring of David, and the bright Morning Star."
Have you seen His star? In 2Peter 1:19 the Apostle speaks of the prophets and to us, to pay attention "to a light shining in a dark place until the day dawns and the morning star rises in your heart." Isaiah foretold of those walking in darkness and seeing a great light, speaking of Christ. This is Peter's admonition, to be moved to receive the "light of the world" into our hearts.
This is why Jesus came to the world, to be a light in the darkness and to lead all willing to find hope in Him. The Magi represented all peoples and were lead to worship the Christ child. They were obedient and followed and God used a star and dream to have them avoid Herod. They were overjoyed when they saw the star again and found the Savior in a house with Mary and Joseph, perhaps two years after His birth. They are included in the Christmas story because of their faith. After they returned home, God used an angel and a dream again to warn Joseph to flee with Mary and Jesus to Egypt.
Yes, God uses many ways to reach and guide us if we will stay open and obedient to His ways that are higher than our's to lead us to a saving faith in Him.
