Before God allowed evil and sin into the world, He had a plan for its removal. It was the shedding of the blood of His Son Jesus. He was the sin offering for humanity - and God accepted it and will take away the sins of the world.
“The next day John sees Jesus coming unto him, and saith, Behold the Lamb of God, which takes away the sin of the world...” (John 1:29)
"He Himself is the atoning sacrifice for our sin, and not ours only, but for the sin of the whole world!" (1 John 2:2)
The plan of salvation is simple, the execution of that plan was harsh, yet God saved His Son out of death and will do the same for all humans at our resurrection.

“And this is the Father's will which hath sent Me, that of all which He hath given Me I should lose nothing, but should raise it up again at the last day...it is finished.” (John 6:39; 19:30)
“For He hath made Him to be sin for us, who knew no sin; that we might be made the righteousness of God in Him.” (2 Corinthians 5:21)
Those who hear and believe the truth of their salvation have peace in this life.
"Peace I leave you, My peace I give you; not as the world gives, do I give to you. Do not let your hearts be troubled, nor fearful." (John 14:27)
All humanity will hear, believe, swear allegiance to God, and confess that Jesus is Lord following their resurrection.
"By Myself I have sworn; truth has gone out from My mouth, a word that will not be revoked: Every knee will bow before Me, every tongue will swear allegiance. Surely they will say of Me, In the LORD alone are righteousness and strength.’ ” (Isaiah 45:23)
"Christ Jesus, Who, as He already existed in the form of God, did not consider equality with God something to be grasped, but emptied Himself by taking the form of a bond-servant and being born in the likeness of humans. And being found in appearance as a man, He humbled Himself by becoming obedient to the point of death: death on a cross. For this reason also God highly exalted Him, and bestowed on Him the name which is above every name, so that at the name of Jesus every knee will bow, of those who are in heaven and on earth and under the earth, and that every tongue will confess that Jesus Christ is Lord, to the glory of God the Father." (Philippians 2:5-11)
Again, humanity cannot save itself from death, but fortunately it does not have to - God will do that.
"...there shall be a resurrection of the dead, both of the just and unjust." (Acts 24:15)
"For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord." (Romans 6:23)
"For as in Adam all die, so also in Christ all will be made alive." (1 Corinthians 15:22)
"For there is one God, and one mediator also between God and humanity, the man Christ Jesus, who gave Himself as a ransom for all, the testimony given at the proper time. For this I was appointed as a preacher and an apostle (I am telling the truth, I am not lying), a teacher of the Gentiles in faith and truth." (1 Timothy 2:5-7)
"This is a faithful saying and worthy of all acceptation. For this we both labor and suffer reproach, because we trust in the living God, who is the Savior of all humanity, especially of those that believe. These things command and teach." (1 Timothy 4:9-11)
