Mark preached about stars last night. God made all the stars (Gen 1:16), including the Seven Sisters constellation:

God placed all the stars in the sky and when we consider the heavens, we are amazed that God is also mindful of us (Ps 8:3-4). The same God who ordained the places of each star, thinks about us.

God counts the stars and calls them by name (Ps 147:4-5); He knows us by name also. God used the star of Bethlehem to guide people to Jesus, causing it to appear at a certain time and move to guide the wise men to the Lord. They came because they had seen His star (Matt 2:1-2) and were aware that it signified the birth of a king (Matt 2:7-11).

The true star of Christmas is Jesus, however. He is the ‘Bright and Morning Star’ (Rev 22:16). He is the greatest gift given by God at Christmas time, so that we should not perish but have everlasting life (John 3:16). He is the King of Kings and Lord of Lords, the One worth celebrating!
