Christmas Questions: Why the Genealogies?

Matthew 1:1-16; Luke 3:23-38

When we read the Scriptures we know and understand that as Paul wrote to Timothy, 'All Scripture is given by inspiration of God and is profitable…" We believe that don't we? We all have certain portions of the Scripture that are favorites. For some it is the Psalms, others love the wisdom of the Proverbs. Still others love to read the Gospels. A few folks love the prophecies. Others favor the historical accounts of the Kings and Chronicles. But very few of us, if we are honest, would say that our favorite portion of the Scriptures is the genealogies.

As a matter of fact, many of us tend to skim over them in order to get to the 'good stuff'. They can be boring can't they? But God said, 'All Scripture'. That means that even the genealogies are inspired, and they are 'profitable'; especially for our question this morning. Why did God choose Bethlehem for the birth of His Son, Jesus? To answer that question, we must turn to the genealogies given for the Lord Jesus.

Genealogies were very important to the nation of Israel. They were essential for practical reasons such as buying and selling property. Land could not be bought and sold across tribal lines, so a person's genealogy was required to validate the sale of property. The entire priesthood also depended on genealogies. All of Israel's priests had to be descendants of Levi.

After the Babylonian captivity, Ezra used the genealogies to determine which priests had a legitimate claim to office. Those who couldn't prove their heritage could not serve as priests.

Perhaps the most important use and purpose of the genealogies was to trace the lineage of Judah's kings went back to David. God's promise was that David's offspring would bring forth the One who would deliver Israel and reign as King. In 2 Samuel 7:16, speaking through the prophet Nathan, God promised David, "And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever."

What this meant was that any claimant to the throne of Israel had to demonstrate genealogically that he descended from David and was in the line of royalty. Scripture records the infallible and authoritative record of that lineage.

Not only do they trace the royal line of Israel, but they also outline God's dealings with His people. They reveal how God's sovereign hand has ordered human events to fulfill His own purposes despite tremendous obstacles. For all those reasons, the genealogies were carefully recorded and guarded. The most important ones were preserved in Scripture. This practice went on for centuries, through the time of Jesus' birth.

In fact, when the New Testament begins, we find Joseph and Mary going down to be registered according to their own ancestry in Bethlehem, their ancestral home. The nation still identified people genealogically.

(Luke 2:3-4) And all went to be taxed, every one into his own city. And Joseph also went up from Galilee, out of the city of Nazareth, into Judaea, unto the city of David, which is called Bethlehem; (because he was of the house and lineage of David:)

I. Two Genealogies

II. Knots in the Family Tree.

III. A Genealogy of Grace

Twas the season of Christmas, and all through the house.
The children asked questions, of me and my spouse.
The first one was why did God become man?
The second was why were the Jews in His plan?
These questions I answered to their satisfaction.
The next one would drive me near to distraction.
In the lineage of Jesus why so many sinners were included?
But as we carefully read His genealogy we concluded.
God doesn't use only those who are good,
But those who are willing and those whom He would.
God used them all as the Scriptures do say
To accomplish His will and to show us the Way.
God uses these knots in Christ's family tree
To remind us that Jesus came to save sinners Like you and like me.
