Does the Bible reveal God's plan for the redemption of humankind, or is it a plan for the genocide/incineration of humanity?
The Bible actually reveals neither for neither is the plan of God.
God never said he would redeem humankind, he said he would redeem those who believed, and this faith existed even in the days of The Law because it was to those who were under The Law that he said, "The just shall live by faith."
Those who cry "faith alone", debunking the Old Testament actually quote it when they say, "The just shall live by faith."
Therefore, by their own definition, it can be said that they live by The Law and are saved by it.
It was always God's plan to offer redemption to those who would believe and receive it through Jesus Christ, yet it was abundantly clear not all would receive it. The Bible clearly says not all will be saved and, also, that not all are condemned.
Humankind died when Adam and Eve sinned. There is no future plan of genocide, only of salvation; but that does not mean those who believe not will not be judged. In fact they are judged of themselves already because they will not believe.
The true gospel says, there is no hope. You are already prepared for the fire, not by God, but by Satan who deceives the whole world. It is he who prepared mankind for the fire. That's Satan's plan, not God's.
Notice that hell and the fire are Satan's dwelling, not God's.
Yet the true gospel says, there is hope if you will believe and, by grace, there is forgiveness of sins through Jesus Christ.
Jesus'parable, which is said to be the parable by which all others can be understood makes this clear.
at 13:24 Another parable put he forth unto them, saying, The kingdom of heaven is likened unto a man which sowed good seed in his field:
Mat 13:25 But while men slept, his enemy came and sowed tares among the wheat, and went his way.
Mat 13:26 But when the blade was sprung up, and brought forth fruit, then appeared the tares also.
Mat 13:27 So the servants of the householder came and said unto him, Sir, didst not thou sow good seed in thy field? from whence then hath it tares?
Mat 13:28 He said unto them, An enemy hath done this. The servants said unto him, Wilt thou then that we go and gather them up?
Mat 13:29 But he said, Nay; lest while ye gather up the tares, ye root up also the wheat with them.
Mat 13:30 Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn.
Notice that the man sowed wheat, not wheat and tares. This is why I do not believe predestination as most say Calvin taught it.
It was his enemy who sowed the tares, in secret, even as Satan did when he tempted Eve. Sin is not God's doing.
Yet God's plan, even as this man, is to save the wheat from among the tares.
The tares suffer what tares always suffer, they are burned because they have no value to the farmer and were not his handiwork.
However the wheat is valued even as God values those that are his.
The choice you make reveals what you are, whether wheat or tare. Those who do not believe are tares and are ready to be burned.
All who repent and believe will be saved. This is the true Gospel for they reveal that they are wheat and that they are the planting of the Lord.
Judgment is not merely coming, it is already upon the world because they will not believe in Jesus whom he sent but it is not God's plan.
God did not plan for man to sin but, when he did, he knew what must be done to save those who are his.
Do you understand the true gospel? Believe in it and be saved out of the world, which is heading for destruction For it is destroyed already, by sin.
