As Nicodemus listened to Jesus describe the life of one filled with the Holy Spirit, he still could not understand. “How are these things possible?” he asked Jesus.
“You are a respected leader in Israel,” Jesus replied, “and yet you do not understand these things?
“I assure you, we are telling you what we know, what we have actually seen. Still, you do not believe our testimony. If you do not believe me when I describe earthly things to you, how can you possibly believe when I tell you about heavenly things? No one has ever gone up to heaven and returned. But the Son of Man, who lives in Heaven, has come down to earth from Heaven.”
In this passage, Jesus very clearly lays out the fact that He was here, on this earth, as a Representative from Heaven. As He spoke of the Kingdom of Heaven, as He revealed His Father, as He described the life born of the Holy Spirit, He was describing His own life and experiences. No one could really understand Him, and most did not believe Him.
So He lived a very lonely life on this earth, a stranger in a foreign land. He was “despised and rejected of men; a man of sorrows, and acquainted with grief.” Even though the birds and the foxes had their homes, He Himself had not even a bed to call His own. We see Him rising very early in the morning to pray to His Father, and sometimes even praying all night. What a lifeline that must have been for Him!
In spite of the loneliness and the rejection, the hatred of the religious leaders, and the lack of understanding in His own disciples, Jesus carried out His mission perfectly, and to the very end. Because He, the Son of Man, Who lived in Heaven “in the Bosom of the Father”, was willing to come to Earth to redeem us, we now have the great Hope and expectation of living in Heaven forever with Him. Because He was willing to experience a tragic life on this earth, He made it possible for us to experience His glorious life in Heaven.
