John 3:16 tells us He died for the Whole World and whosoever [[((BELIEVES))]] will be Saved.
so the Father gave the entire World to Jesus. but only a few will Believe!
So, your response is John 3:16. Let's review the Scripture.
“
For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life."
Both reformed and non-reformed Christians agree that "whosoever believes in Christ" will be saved. Period. End of story.
This doesn't speak in any way to man's natural ability to choose Christ in his unsaved state.
When we look at the passages of Scripture that specifically speaks to man's ability to choose without a specific act of God working in him, we see a resounding no, man is so steeped in his sin he cannot respond in the positive to Christ, not in truth. For sin yes, money, power, position, reputation etc. But not simply for love of God.
And you were dead in the trespasses and sins in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind. But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved— and raised us up with him and seated us with him in the heavenly places in Christ Jesus.
God took what was dead, made us alive and raised us up with Jesus and seated us, by Grace you have been saved.
God - not man making a good choice.
The conversion of Lydia in Acts shows this clearly.
On the Sabbath we went outside the city gate to the river, where we expected to find a place of prayer. We sat down and began to speak to the women who had gathered there. One of those listening was a woman from the city of Thyatira named Lydia, a dealer in purple cloth. She was a worshiper of God. The Lord opened her heart to respond to Paul’s message. When she and the members of her household were baptized, she invited us to her home. “If you consider me a believer in the Lord,” she said, “come and stay at my house.” And she persuaded us. Acts of the Apostles 16:13-15
The Lord made her able to respond, and she was saved.
everything the Bible teaches us is that we have no natural ability to respond positively to Christ. We are so steeped in our sin, sin is the object of our natural desire and it literally takes God to change our very desire, our heart and our minds, to save us out of that.
Jesus is now putting His enemies under His feet (Psalm 110:1), who wouldn't have enemies at all if everyone born was in Covenant. There's a general calling being given to everyone the Church can reach, and
some from every tribe, nation and tongue will be saved..
But those who remain unsaved to death will always choose sin. They have no natural ability to choose anything else, their only desire is for sin... And they want it with everything they are, happily, willingly.
Another thing to consider is how John uses the term “the world” in John 4:42.
Many Samaritans from that town believed in him because of the woman’s testimony, “He told me all that I ever did.” So when the Samaritans came to him, they asked him to stay with them, and he stayed there two days. And many more believed because of his word. They said to the woman, “It is no longer because of what you said that we believe, for we have heard for ourselves, and we know that this is indeed the Savior of the world.” John 4:39-42
In this passage, when the Samaritans say that Jesus is the “Savior of the world,” they are saying that Jesus is the savior of
not only the Jews, but also the Gentiles. They are surprised that Jesus would reach out to a Samaritan woman, when Samaritans were looked down upon by the Jews.
It simply makes far more sense to believe that the Samaritans are using the word “world” to refer to not only the Jewish group of people, but also people who were not Jews (for example, the Samaritans), than that they are referring to every individual person in the world.
Thus, we can conclude that if John is using the term “the world” in this fashion in John 4:42, it is more likely that he is also using this sense of “the world” (“not just the Jews, but also the Gentiles”) in other places (for example, in John 3:16) than that he is using it to refer to “every individual person” in other places.
Jesus' Covenant is with the saved, and only the saved. It's not with everyone. And salvation of souls is an act of God, He chooses His disciples.
