One of the great mysteries contained in the Bible is that it teaches that Jesus is fully God and also that He is fully man. The kenosis (from the Greek kenoō, meaning “to empty”) refers to Jesus willingly setting aside His divine privileges to become fully human while remaining fully God (Philippians 2:5–8). In this act, Christ did not cease to be God but chose to humble Himself, taking the form of a servant and depending entirely on the Father. He laid aside His heavenly glory (John 17:4–5), His divine rights (2 Corinthians 8:9), and His independent use of divine knowledge (John 8:28) to live in perfect obedience and sacrifice for humanity. The kenosis reveals the depth of God’s love—Jesus emptied Himself to lift us up. Jesus’ example teaches us to humble ourselves, let go of pride and privilege, and serve others with the same self-giving love that led Him to the cross (Mark 10:45; 1 Peter 2:21).
The kenosis of Christ is His emptying Himself of certain divine privileges to become a servant for those He loves. But it is important to understand what this passage means and does not mean. What exactly did Christ empty Himself of? There are at least four things that Jesus willingly gave up to become that Child in the manger:
First, He emptied Himself of His pristine position in relation to the Law. Although not personally guilty of any sin, Jesus willingly took the sins of the world (1 John 2:2). Paul makes this clear when he writes, "For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God" (2 Corinthians 5:21).
Second, He emptied Himself of His rightful ownership of everything. Although He created everything, Jesus had to borrow a place to be born, places to sleep, boats to preach from, an animal on which to ride into Jerusalem, a room in which to eat the Last Supper, and a tomb in which to be buried.
Third, He emptied Himself of His heavenly glory that He shared with the Father. Right before His arrest, Jesus prayed, "I glorified you on earth, having accomplished the work that you gave me to do. And now, Father, glorify me in your own presence with the glory that I had with you before the world existed" (John 17:4–5).
Finally, Jesus emptied Himself of His divine knowledge. This required Jesus to rely solely on the Father for what He knew. And that's why Jesus, although He is God, "did not know" when His second coming would occur (see Matthew 24:36). He had voluntarily given up that knowledge to live life as a man.
With the kenosis, Jesus provided an example of how we all should live – in complete dependence upon God for everything, including the knowledge and wisdom that we need.
So, did the baby in the manger know that the world was round? In His divine nature, yes, Jesus knew that fact. But during the time of His earthly ministry, He willingly emptied Himself of numerous divine privileges. Thus, in His human nature, He did not have that immediate knowledge.
The lesson for us is that we should reflect our Master. Whatever supposed privileges we possess or whatever we think we deserve should be set aside in our service to others. Jesus did not cling to His heavenly throne; why should we cling to earthly treasures? We must be willing to empty ourselves, just as Jesus did, for God’s glory and for the good and love of others.
