“For God did not send His Son into the world to condemn the world, but that the world through Him might be saved.”  John 3:17
 
In the Gospel of John we find several verses where Jesus tells us of His being sent by God:
“For I have come down from heaven, not to do My own will, but the will of Him who sent Me.”  John 6:38
 
“But I know Him (the Father), for I am from Him, and He sent Me.”  John 7:29
 
“Jesus said to them,  ‘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.”  John 8:42
 
“I must work the works of Him who sent Me while it is day; the night is coming when no one can work.”  John 9:4
 
Speaking to the Jews,
“Do you say of Him whom the Father sanctified and sent into the world, ‘You are blaspheming’ because I said, ‘I am the Son of God?’”  John 10:36
 
In Jesus priestly prayer to the Father,
“For I have given to them the words which You have given Me; and they have received them, and have known surely that I came forth from You; and they have believed that You sent Me.”  John 17:8
And, Vs. 21,
“That they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me.” 
 
The Son was sent for the purpose that the world be saved through Him.
It is the saving power of God through Jesus!  
 
We have redemption and forgiveness through Jesus:
“In Him we have redemption through His blood, the forgiveness of sins, according to the riches of His grace.”  Ephesians 1:7
 
“He has delivered us from the power of darkness and translated us into the kingdom of the Son of His love, in whom we have redemption through His 
blood, the forgiveness of sins.”  Colossians 2:13-14
 
We are justified (no longer guilty) through Jesus:
“Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ.”  Romans 5:1
 
In His power we are reconciled (we now have fellowship with our Father) through Jesus:
“For if when we were enemies we were reconciled to God through the death of His Son, much more, having been reconciled, we shall be saved by His life.  And not only that, but we also rejoice in God through our Lord Jesus Christ, through whom we have received the reconciliation.”  Romans 5:10-11
 
By God’s power we are sanctified (set apart as His child) through Jesus:
“Then He said, ‘Behold, I have come to do Your will, O God’…by that will we have been sanctified through the offering of the body of Jesus Christ once for all.”  Hebrews 10:9-10
 
The work that Jesus was sent to do, He accomplished:
“I have glorified You on the earth, I have finished the work which You have given Me to do.”  John 17:4
 
John 19:28-30 gives us the last scene of incarnate Jesus’ work,
“After this, Jesus, knowing that all things were now accomplished, that the Scripture might be fulfilled, said, ‘I thirst!’
Now a vessel full of sour wine was sitting there; and they filled a sponge with sour wine, put it on hyssop, and put it to His mouth.
So when Jesus had received the sour wine, He said, ‘It is finished!’  And bowing His head, He gave up His spirit.” 
 
In Romans 8:28-30 we have these awesome words of assurance:
“And we know that all things work together for good to those who love God, to those who are the called according to His purpose.
For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren.
Moreover whom He predestine, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.”  
 
Thank you Father for sending Jesus.  Thank you Jesus for finishing the  work You were sent to do.  Thank you Holy Spirit for dwelling in each Believer.  How awesome You are most holy Lord God Almighty and how grateful we are!.  Amen  
 
So we sing:
“I will give thanks to the Lord with my whole heart,
I will tell of Thy wonderful deeds,
I will be glad and exalt in Him,
I will sing praises to Thy name,
O most High.”
