Salvation has been provided for everyone, it is a free gift from God, Hebrews 2:9 also Romans 5:15-19.
If you neglect or reject what God has provided for you in Jesus Christ then you will send yourself to hell. As far as I can see you are already there.
If salvation is provided for everyone as you claim, then all will go to heaven and it matters not whether a person neglects or rejects. All are saved.
If you claim that salvation is dependent upon our own actions, then you are preaching the law as a means of salvation with no need for God's grace.
Let's look at Hebrews 2. Perhaps you failed to read past verse 9. If you had you would see that God choses who will be saved.
Hebrews 2:9-13
[9]What we do see is Jesus, who was given a position “a little lower than the angels”; and because he suffered death for us, he is now “crowned with glory and honor.” Yes, by God’s grace, Jesus tasted death for everyone.
[10]God, for whom and through whom everything was made, chose to bring many children into glory. And it was only right that he should make Jesus, through his suffering, a perfect leader, fit to bring them into their salvation.
[11]So now Jesus and the ones he makes holy have the same Father. That is why Jesus is not ashamed to call them his brothers and sisters.
[12]For he said to God, “I will proclaim your name to my brothers and sisters. I will praise you among your assembled people.”
[13]He also said, “I will put my trust in him,” that is, “I and the children God has given me.”
Look at Romans 5. There is no universalism being taught by Paul. It seems you are struggling to accept that God is Sovereign, not you.
Romans 5:15-21
[15]But there is a great difference between Adam’s sin and God’s gracious gift. For the sin of this one man, Adam, brought death to many. But even greater is God’s wonderful grace and his gift of forgiveness to many through this other man, Jesus Christ.
[16]And the result of God’s gracious gift is very different from the result of that one man’s sin. For Adam’s sin led to condemnation, but God’s free gift leads to our being made right with God, even though we are guilty of many sins.
[17]For the sin of this one man, Adam, caused death to rule over many. But even greater is God’s wonderful grace and his gift of righteousness, for all who receive it will live in triumph over sin and death through this one man, Jesus Christ.
[18]Yes, Adam’s one sin brings condemnation for everyone, but Christ’s one act of righteousness brings a right relationship with God and new life for everyone.
[19]Because one person disobeyed God, many became sinners. But because one other person obeyed God, many will be made righteous.
[20]God’s law was given so that all people could see how sinful they were. But as people sinned more and more, God’s wonderful grace became more abundant.
[21]So just as sin ruled over all people and brought them to death, now God’s wonderful grace rules instead, giving us right standing with God and resulting in eternal life through Jesus Christ our Lord.
