I've never been baptized and I've had many tell me because of this I won't get into heaven.
If God is wiling to forgive criminals and murders why would he turn his back on me?
well, first of all, do not listen to people. they will always lead you astray with rare exception.
next, read old and new testaments simultaneously - a chapter of matthew, then genesis, then psalms , then luke, then john and so on
as you are able to , as god permits and delights in your life seeking him,
and
ask god to show you why he rejects who he rejects, and why he receives who he receives. he is in charge,
and he will tell you if he wants to.
if he doesn't want to , then no one will be able to either.
no one else besides jesus has the words of eternal life. this is written. this is unchangeable. this is forever true.
so ask him. listen to him. spend time with him frequently, listening to him as well as telling him everything and asking him every day for what you need.
he will answer you and lead you to life, or he will harden your heart so you cannot find life -- one or the other. and only he knows
what is going to happen every day of your life, and only he is able to save you. no one else can, ever.
he does have a promise or 2 (or 1000) , indicating or telling you directly, how you may receive life and life abundantly(with joy, and with peace, and with righteousness as well as eternal life; all without merit and literally for no reason at all except he chose you. and if he is for you. if he gives you life. if he choses you,
then no one can take you away from him....... except yourself. that's why he wrote in the bible "work out your own salvation with fear and trembling" and again "be afraid lest any of you should fall short..."
but you'll have to see this in scripture yourself to gain anything at all from God.....
and if you do, then you will have the most amazing joy and peace that you have ever dreamed about....
but if you get distracted with what people say about you, and not what God says about you,
well, let's just say that then you won't have so much peace..... and leave it at that for now..... it hurts too much to think about.
rather simply and always seek him, and as a good shepherd who lays down his life for the sheep, he will guide you himself --- that is his promise in his word, the bible.
