Gospel of our Salvation
Ezekiel 3:
18 When I say to a wicked person, ‘You will surely die,’ and you do not warn them or speak out to dissuade them from their evil ways in order to save their life, that wicked person will die for[Or in; also in verses 19 and 20] their sin, and I will hold you accountable for their blood. 19 But if you do warn the wicked person and they do not turn from their wickedness or from their evil ways, they will die for their sin; but you will have saved yourself.
20 “Again, when a righteous person turns from their righteousness and does evil, and I put a stumbling block before them, they will die. Since you did not warn them, they will die for their sin. The righteous things that person did will not be remembered, and I will hold you accountable for their blood. 21 But if you do warn the righteous person not to sin and they do not sin, they will surely live because they took warning, and you will have saved yourself.”
James 5:
19 My brothers and sisters, if one of you should wander from the truth and someone should bring that person back, 20 remember this: Whoever turns a sinner from the error of their way will save them from death and cover over a multitude of sins.
Romans 10:
14 How, then, can they call on the one they have not believed in? And how can they believe in the one of whom they have not heard? And how can they hear without someone preaching to them? 15 And how can anyone preach unless they are sent? As it is written: “How beautiful are the feet of those who bring good news!”[Isaiah 52:7]
16 But not all the Israelites accepted the good news. For Isaiah says, “Lord, who has believed our message?”[Isaiah 53:1] 17 Consequently, faith comes from hearing the message, and the message is heard through the word about Christ. 18 But I ask: Did they not hear? Of course they did:
John 6:63
The Spirit gives life; the flesh counts for nothing. The words I have spoken to you—they are full of the Spirit and life.
John 5:25
Very truly I tell you, a time is coming and has now come when the dead will hear the voice of the Son of God and those who hear will live.
2 Corinthians 5:
16 So from now on we regard no one from a worldly point of view. Though we once regarded Christ in this way, we do so no longer. 17 Therefore, if anyone is in Christ, the new creation has come:[Or Christ, that person is a new creation.] The old has gone, the new is here! 18 All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation: 19 that God was reconciling the world to himself in Christ, not counting people’s sins against them. And he has committed to us the message of reconciliation. 20 We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God. 21 God made him who had no sin to be sin[Or be a sin offering] for us, so that in him we might become the righteousness of God.
I believe God made us the messenger of Christ and His word and the message brings man to the state of Adam. To believe God don't eat from the tree and live or now trust in His Son and live or not and be condemned. It is simple, but men complicate it. Christ word regenerates, renews if we reject it we reject life. Those who didn't trust in Christ was cut out of what they were already in and those who trusted in Christ remained and those who were not in it from the beginning was included when they heard the Gospel of their salvation having believed. The elect is simply those who trust in Christ.
