What if I don't know him and he doesn't know me? The way the bible makes it sound is God has people picked out to be with him from the beginning of time? Like "chosen" ones? So if he already knows who is going to be good or bad why torment the rest of us and have us burn for an eternity? Should had never made us in the first place because that is crap man... I have prayed for forgiveness of my sins, repented and was baptized as a baby and asked to be filled with the holy spirit. but then bad things just start happening like God is saying "I don't want you, you will never enter my kingdom!"
I'll try to answer every question and provide few verses so read till the end .
Your questions are very very common and most of people ask them from my personal experience and it's because of lack of knowledge of the Bible and lies spread around world from different denominations every claiming that they got the "truth" and that their point of view is the correct one making huge mess and divisions that's why I suggest to read the Bible for yourself and you will find most answers for your questions here .
1)What if I don't know him and he doesn't know me?
If you don't know him or he doesn't know you then you will suffer for eternity in the future after you will be ressurrected from the dead.
There are 2 types of ressurection , one of living and then of the damned to be judged and punished , people in first ressurrection are not judged because their sins were alredy judged at the cross and forgiven by Christ , people in 2nd ressurrection are punished for not accepting Holy Spirit and forgivness from God . Revelation 20:5-15
2)The way the bible makes it sound is God has people picked out to be with him from the beginning of time?
God did not pick anybody because we have free will , he just know who would believe and accept Holy Spirit so he send them preacher so they can hear the news and be saved.
And it's called grace because it's free plus God does not owe us anything so it's his mercy .
People "picked" this way are called "not from this world " because they were rescued from this fallen world . John 17:16
3)
So if he already knows who is going to be good or bad why torment the rest of us and have us burn for an eternity?
This is major misconseption that most people believe just like they imagine satan being like devil with horns and pitchwork ruling in underworld in hell .
People don't go to heaven into eternity for being good or bad
Bible is pretty clear on this topic that there is not one person righteous and good , God himself call us evil and that none made it and none kept his laws .
Mark 10:18
Romans 3:10
Romans 3:23
There are no "levels" of sin , murder is not more sinful than telling lie in God's eyes if you commited one sin you are guilty of every single one and not better or worse from your friend who commited other sins.
James 2:10
People go to heaven/are forgiven on basic of if they accepted Jesus Christ or if they rejected him and it's free. Ephesians 2:8-10 , Romans 11:6-8 , Ephesians 1:13-14 , 1 Corinthians 15:1-4 .
4.I have prayed for forgiveness of my sins, repented and was baptized as a baby and asked to be filled with the holy spirit. but then bad things just start happening like God is saying "I don't want you, you will never enter my kingdom!
a) Jesus died for sins therefore asking for forgivness is like asking Jesus to go suffer for you again because first time was not good enought it's not Biblical , there is no sinner's prayer in Bible it's man made, feeling bad for commiting sin and wanting to do good is very good thing but it has nothing to do with being saved and having eternal life
b) Repentance is change of mind , it does not mean stopping doing one sin , if you commited 1 sin you are alredy sinner for rest of your life.
Murderer who killed somebody can't plead before judge that he will never kill somebody again so he should let him go not punished for what he commited , God is just Judge so he has to punish sin
What repentance in Bible is , it's change of mind from being wicked person going to hell towards wanting to have relationship with God and be saved. Some person can be presented with clear gospel and reject it therefore rejecting salvation
That should give you enought information about gospel and answer your questions , remember the things you said you did like being baptised as baby , going to church ect does not make you a Christian to begin with , what makes somebody Christian or "the elect " is if he has been sealed with Holy Spirit after accepting free gift of salvation .
