“Behold, the virgin shall be with child, and bear a Son, and they shall call His name Immanuel,” which is translated, “God with us.” (Matthew 1:23)
When Christ came to earth, He came as a human born of a woman. He was fully human and still fully God, but why is this so important?
For since by man came death, by Man also came the resurrection of the dead. For as in Adam all die, even so in Christ all shall be made alive. (1 Corinthians 15:21–22)
For if by the one man’s offense death reigned through the one, much more those who receive abundance of grace and of the gift of righteousness will reign in life through the One, Jesus Christ.) . . . For as by one man’s disobedience many were made sinners, so also by one Man’s obedience many will be made righteous. (Romans 5:17,19)
Because sin came through one man—our father Adam—we all inherit a sinful nature. Since sin was brought into this world by a man, it had to be removed by a man. If Christ had come as just a spiritual being, then He could not have been sacrificed and had His blood spilled. Christ was a blood sacrifice for us, since “without shedding of blood there is no forgiveness” (Hebrews 9:22, NASB). If Christ had just been a spiritual being—and not 100 percent man—He would not have had blood to spill, and thus we could not have been truly cleansed from our sins.
Just as Adam and Eve needed a living sacrifice (requiring the shedding of blood) to cover their sin, so we have a covering that takes away our sin in a way no animal sacrifice ever could (Hebrews 10:4).
For there is one God and one Mediator between God and men, the Man Christ Jesus. (1 Timothy 2:5)
Jesus became a member of the human race and is the only Mediator between God and man. Because He was fully human, we could see our own sufferings in Him, for He endured the same types of trials as we face, and He persevered under great physical pain. We can identify with Him since He was fully human (Hebrews 2:14). He suffered pain and endured emotions so He could relate to and sympathize with us (Hebrews 4:15).
Jesus became a man to die for our sins, because our substitute needed to be fully human to take humanity’s place. As a descendant of Adam, He was our blood relation, so He can be our “kinsman redeemer” (Isaiah 59:20, same word in Ruth 2:20).
Christ had to be fully human in order to die, pay for our sins, and redeem us.
Thank God because He sent a “kinsman redeemer” so we could be saved from His wrath.
