Be Authentic Like Jesus | Proofs about Christ

Was Jesus really born the Son of God?

This is the question many around the world are still asking. In today’s Bible reading, Jesus, the apparent illegitimate son of Mary, is claimed to be the Messiah, the Son of God. That seems hard to believe. The unspoken but very loud question in people's minds is, “what proof do we have?” In Jesus' day they did not have Driver's Licenses, Social Security cards or any other modern method to prove identity, so how can it be proved that Jesus is the Son of God?

Genealogical Records

In the Jewish society of that time, genealogical records proved your lineage and demonstrated your rights of inheritance. In the book of Matthew, Jesus’ family tree is traced through Joseph, his legal father, from Abraham through David’s line. Jesus is Jewish, and through the line of Abraham all nations will be blessed (Genesis 12:1-3). Through the line of David, Jesus has the right to reign (Genesis 49:9-10; Jeremiah 23:5).

In the book of Luke, Jesus’ genealogy is traced through a different line. It is traced backwards from Jesus’ adopted father, Joseph, to the first man of creation, Adam, and then finally to God. In this account, Joseph's father is said to be Heli, not Jacob. The contributing author in states that there is no word for father-in-law in the ancient Greek language, and so it is likely that Jesus' lineage is traced through Mary's line, Heli being her father.

Jesus was always one with God in heaven, but in his mercy and grace he leaves heaven’s glories and is miraculously conceived in Mary, a virgin (Philippians 2:6-7; John 1:14; Matthew 1:20-23). When he is conceived, Jesus takes on Adam’s flesh (humanity). Both genealogies have some common ancestors, two being King David and Abraham. By legal right and natural lineage Jesus is the Messiah the Jewish people are seeking.

Historical Records and Dates

These prove the probability of the Bible story. A prosecuting attorney might ask a defendant, “Where were you at such and such a date?” He tries to break down the testimony of the defendant, but if the defendant's testimony is true then the true facts are supplied. The first four books of the New Testament are filled with exact times, names of historical characters, and events around the time of Jesus' birth. If his birth is a lie, why not hide the truth? Facts of history can be easily proved or disproved. Luke 3:1-2 records the time of John the Baptist’s ministry. He prepares the way for Jesus. Luke 2:1-2 records the time of Jesus’ birth.

Fulfilled Prophecies

They testify to the truth of the gospel's claims. As we learned yesterday, Malachi 4:5-6 and Luke 1:17 testify to fulfilled Scriptures concerning John the Baptist being forerunner to Christ. Isaiah 7:14 and Matthew 1:20-23 testify to fulfilled Scriptures concerning the virgin Mary having a baby who would be the Jewish Savior and Immanuel. Immanuel means “God with us” —he will be physically present with his people. Micah 5:2 and Luke 2:4-7 testify to where Jesus would be born (in Bethlehem), and that he will be ruler over Israel, which is in the future (Revelation 19:6-16).


A testimony of two or three reliable witnesses is sufficient in our courts to establish truth as it was in Jewish society (Deuteronomy 19:15; Matthew 18:16; and 2 Corinthians 13:1). Jesus had many more than that. In Luke 2-3 there are testimonies of the shepherds, the righteous man Simeon, and the prophetess Anna. Matthew 2 records the testimony of the magi who come from the east, bearing expensive gifts for the Christ child. They said that they have seen his star in the east and have come to worship him, the king of the Jews (Matthew 2:1-2). Later, at the beginning of Jesus' ministry, John the Baptist hears the voice of God giving testimony at Jesus’ baptism. All those present at the Jordan River that day also hear it. John testifies that he saw the Holy Spirit descend on Jesus in the form of a dove. By that sign previously revealed to him, he knows and testifies that Jesus is the Lamb of God who takes away the sin of the world, (John 1:29-34). Even Jesus’ enemies later recognize his integrity. The Herodians (a political party loyal to King Herod) admit to Jesus, “Teacher, … we know you are a man of integrity and that you teach the way of God in accordance with the truth. You aren't swayed by men, because you pay no attention to who they are” (Matthew 22:16 NIV).

We have learned that Jesus is authentic by his lineage, historical records, fulfilled prophecies, and testimonies about him. What about us? How authentic are we? We do not carry identification cards saying we are Christians, but have we been miraculously born of God by his Spirit? Have we been saved by grace through faith? We may not carry a card, but if we are saved, we are sealed by his Spirit until the day of redemption (Ephesians 4:30). Can our neighbors testify that we are Christians? Are we truthful, accountable and reliable? Do we behave and act with integrity? Are we sacrificial in our love? Children grow to be like their parents most of the time. Are we showing ourselves to be more and more children of God, in favor with God and men, as Jesus was?

Lessons to Live By

  • Jesus came to save the Jews and us from our sins. He offers us spiritual life, forgiveness, peace with God and his favor (more...)
  • Christians, we need to be authentic. Let's be genuine followers of Jesus—people of integrity, present with others in their needs, and serving and willing to make sacrifices.
