Summary: The purpose of the Lord's coming was to make sure that no one perishes.
The love that God as for man kind is an unconditional love and this love of God is unchangeable. God loves every race, for He created us all in His own image and likeness - Genesis 1: 26 - 27. God is who He says, He is and can never lie to us His children. God did not want any of us to be without the knowledge of knowing Him as our God and this is why we know that the love that He as for us is a love that can never be taking for granted.
God is love and love is God. We are all children that was created in His love. Because of this wonderful love of God, He does not want anyone to not know Him as God. God is a good God and a good God would not want His children to fall into the trap of the enemy, Jesus rightly said to us in John 8: 44 - 45
John 8: 44 - 45
You are of your father the devil, and it is your will to practice the desires [which are characteristic] of your father. He was a murderer from the beginning, and does not stand in the truth because there is no truth in him. When he lies, he speaks what is natural to him, for he is a liar and the father of lies and half-truths. But because I speak the truth, you do not believe Me [and continue in your unbelief].
And in 2 Corinthians 3: 14
But [in fact] their minds were hardened [for they had lost the ability to understand]; for until this very day at the reading of the old covenant the same veil remains unlifted, because it is removed [only] in Christ.
Also in 2 Corinthians 4: 3 -4
But even if our gospel is [in some sense] hidden [behind a veil], it is hidden [only] to those who are perishing; 4 among them the god of this world [Satan] has blinded the minds of the unbelieving to prevent them from seeing the illuminating light of the gospel of the glory of Christ, who is the image of God.
The truth of the coming of Jesus Christ is been hidden by Satan who is the god of this world, and many are still been blinded by Him so that they will not be set free from His kingdom and brought to a knowledge of the truth of Jesus, who is the Saviour of the world. The word of God says this to us in the book of Colossians 1:13 that "God For He has rescued us and has drawn us to Himself from the dominion of darkness, and has transferred us to the kingdom of His beloved Son",
God through the coming of His Son took us out of the kingdom of Satan and God Himself brought us into the kingdom of His Son - He took us out of the kingdom of darkness into the kingdom of light. But like we said many are still in the kingdom of darkness, while God in His love has done all that He could by sending His Son to be our Saviour.
In God's unfailing love, He is still drawing us out of the realm of darkness into His kingdom, we are to accept the finished work of Jesus Christ and be partakers of the kingdom of light.
Jesus said to us in the scriptures several times that He came to seek out those that are perishing
And there is salvation in no one else; for there is no other name under heaven that has been given among people by which we must be saved [for God has provided the world no alternative for salvation].”
Jesus said to him, “[a]I am the [only] Way [to God] and the [real] Truth and the [real] Life; no one comes to the Father but through Me.
No one can come to Me unless the Father who sent Me draws him [giving him the desire to come to Me]; and I will raise him up [from the dead] on the last day.
Salvation belongs to the Lord;
May Your blessing be upon Your people. Selah.
He who has believed [in Me] and has been baptized will be saved [from the penalty of God’s wrath and judgment]; but he who has not believed will be condemned.
I am not ashamed of the gospel, for it is the power of God for salvation [from His wrath and punishment] to everyone who believes [in Christ as Savior], to the Jew first and also to the Greek.
Jesus' purpose for coming was to reveal His father to us and to bring us into a relationship with Him. We are to believe in Jesus as our Saviour and Redeemer. He came to show us the way back to the Father and He said this in John 14: 1 - 6
