"This is the work of God, that you believe in Him who He sent." John 6:29. This scripture is the reason God sent His Son Jesus to earth.So that we could have the opportunity to believe on "Him (Jesus) whom He (The Father) sent. I could even say that this is the reason we were born.. Just to have this opportunity. Please read John 3:16,17 and 18. Now read 2Corinthians 5:21 "For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him." You see God The Father made Jesus, who knew no sin, to become sin for us, so that we could become the righteousness of God in Him (Jesus). In John 8:42, Jesus said "If God were your Father, you would love me, for I proceeded forth and came from God; nor have I come of Myself, but He sent Me. Now lets read  John 5:24 "Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgement, but has passed  from death into life. Now lets read John 17:3 "and this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent."This is  the reason that God The Father sent His Son Jesus into the world.And once Jesus delivered this message He left the world. But before He left this world, He was crucified on the cross, shed His Precious Blood, died, and rose from the dead. Jesus is the Son of God, the Prince of Peace, the King of kings and the Lord of lords. He is the wonderful counsilor. The light of the world and the great I Am. He is the Alpha and the Omega, the Begining and the Ending. Which is,and which was,and which is to come.The Almighty.He is the Spirit of Truth, the Word of God, the Word of life.crucified and risen. He is the precious Son of God,who proceeds out from the Father,and He shed his precious Blood for us.He was wounded for our transgressions,bruised for our iniquities;The chastisement for our peace was upon Him,and by His stripes we are healed.
