Genuine curiosity. They’re questions, not attacks. Even the pastor in the video said he gets those questions often.
I understand. It is a common enough question but it is a common enough answer. Yes, there are hardline christians that will say unless you are baptized going face forward, you are not going to heaven. And some that say you must say a prayer a certain way in order to go to heaven. The language of some christians is exhausting, and many of those same christians live a life far from what Jesus lived or asked anyone to live, lives that Jesus even chastised and mocked. This type of pure legalism, meaning the manner in which something is done is as important as the thing done, is almost a 180 degree viewpoint from what Jesus preached and lived. He wanted relationship, compassion, and love to rule the day. He said this is the way the Father wants things too.
So the genuine answer to your question is this: we humans really do not know the answer. We can think we do, or we can act like we do, but the bottom line is none of us are God and none of us can experience anything like the love God has for each and every one of us. He chases after us. He seeks us when we are lost, and celebrates when He finds us. In Burkes book on NDEs, it even seems He gives some people the chance while right in front of Him to choose love. There is enough mystery surrounding the path to eternity that most Christians simply say they know a path and it is what Jesus taught.
While Jesus said "no one will come to the Father except through me" it is quite possible He was simply referring to Him being the blood sacrifice God demands to redeem sin, and since Jesus did that, we are all welcome if we choose....and when that choice is made is totally up to God. Too many people get caught up in the "pre-death" vs "post-death" as if it means they won't get to heaven if someone else does. Such nonsense. Any true follower of Jesus would rejoice if someone who died and was not a believer turned into one in the last hour of their life, the last minute, or in the first period of the afterlife when they meet God.
Does this mean I do not believe in hell or that people will be there? I 100% believe in the place Jesus referred to as the fiery pit (some call this hell, others the pit prison) where there is eternal torment and gnashing of teeth, and that there are people there, or at least beings. We have to be very careful to say something that is not in line with what Scripture says, as I believe the Bible is infallible and also without contradiction. So if Jesus said something, it is true. But there might be nuance to what is written and sometimes what is written is not the full extent of the story, because maybe we humankind simply cannot begin to grasp or understand the reality of what is being said or written. I do not think any human should say any other human is going to hell though. It is not our place to judge. That is solely God/Jesus/Holy Spirit place to judge.
Does that help at all?
Edit for clarity: I do not read the Bible and say it is nuanced and open to interpretation by each individual. I believe there are some things that are doctrinal and not open to interpretation, but at the same time some things are taken by humans for humanistic purposes (fear, money, membership roles) and spun out of what the text actually says to manipulate people. We have be very wise and read the Bible in context of the story it tells. And taking a single verse or two and quoting those only is very ripe for mainpulative practice. I always read the chapter, and sometimes more, which contain the verses quoted to get the context of the greater picture being told by those verses.
