1. God's Word is true

Prophecy will come to pass. Christ fulfilled the Old Testament prophecies. He came from the line of David who was the King of Israel. As prophesied in Isaiah 11:1, “And there shall come forth a rod out of the stem of Jesse, and a Branch shall grow out of His roots.” Joseph was from the lineage of David, Luke 2:4. Christ is the true Messiah. Isaiah predicted that the Messiah would come as a suffering servant who would be oppressed and afflicted. Isaiah 53:7.

2. God is not limited by background

Jesus was born in Bethlehem of Judea, to Joseph and Mary. Even though Bethlehem was a small town, the Lord chose the city as the birth place of Jesus. 

“But thou Bethlehem Ephratah, though thou be little among the thousands of Judah, yet out of thee shall he come forth unto me that is to be ruler in Israel; whose goings forth have been from of old, from everlasting.” Micah 5:2. 

Joseph and Mary were humble Nazarenes. Nothing much is said about them. By profession, Joseph was a carpenter and Mary, a simple maiden. They trusted the Lord. God can use anyone no matter their background. Mary did not question the angel, Gabriel who visited her. She believed. Mary seems to have known the scriptures about the coming Messiah. God will work out His plan using anyone He chooses.

Jesus was born in a manger as mentioned by the angel Gabriel, “And this shall be a sign to you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger.” Luke 2:12. There was no room for Him except for the manger. Christ can identify with all kinds of people, the rich and the poor. He understands everything going on in our lives. He wants to dwell with us. His name, "Emmanuel" means, "God with us.” He is with us in our suffering and in our sorrows.

3. God can reveal Himself to anyone

The three wise men from the East, and the humble shepherds were among the first people to witness the birth of Christ. The angel appeared to the shepherds at night with good tidings, 

“For unto you is born this day in the city of David a Savior, which is Christ the Lord.” Luke 2:11.

The shepherds accepted this great news with gladness, and went to worship the Messiah. They even told the news of the birth of Christ everywhere.

The three wise men followed the star until they came to the place where the baby was. They were glad, “When they saw the star, they rejoiced with exceeding great joy.” Matthew 2:10. The wise men were glad to have finally found the Savior. When we seek the Lord, we will find Him. Jeremiah 29:13.

Just like Joseph and Mary, we can also be used by God if we fully surrender our lives to Him.
