There's a lot here so let me touch on a few points. From what I read I am in agreement with you. GotQuestions seems to be mainline type Evangelical Billy Graham stuff. Not that I dislike these folks nor am I saying they are not good Christians, but there's some things they simply have wrong. First off, I would not say I believe in a second chance. However... I did not say one can't be saved after death, either. But that may be their first chance after the resurrection. Compare Ezekiel 37 where God puts His Spirit in those dry bones after a physical resurrection. That's Israel after the Millennium and the Great White Throne judgement is a period (millennium-like) after the resurrection that Revelation states that will occur afterwards commonly called the "General Resurrection" which are really two more (Daniel 12:2), but I digress. So, in Revelation at the Great White Throne judgment the books (the Bible) are opened and people are judged by their works. This was assumed that they all "went to hell" since nobody is saved by works, but I did notice one thing that bothered me. The book of life was opened, too. Whoever was not written therein was thrown into the lake of fire to be destroyed forever in the second death. So, these people, resurrected later, did have a chance at salvation. Who are they? Babies who died, people who never heard the Word of God, people whose lives predated Christ, etc etc. and those who never had that chance. You get the idea and the Lord has all bases covered so that EVERYONE has a chance to come to Christ which is the only way to be saved. Nobody is left out. Not even Hitler (theoretically), but I do believe the resurrection of the incorrigibly wicked are thus thrown in the lake of fire - they made their choice.
As with many Christian groups, the problem is that Greek (and other) paganism mixed in biblical doctrine. Remember where our Lord said that the eye is the lamp of the body? But if the eye is evil then your whole body will be full of darkness. He was talking about perspective. If what we see (or hear) is going through the sludge and slime of paganism, then our whole doctrine will be corrupt. So one has to filter that out. This is why I like to get back to the Judaic brand of Christianity and obedience (to what the Spirit enables me and as long as I filter out temptations) to God's Law in which well-meaning but severely misinformed Christians "warn" me I'm trying to be saved by the Law. No I'm not. But the alternative is believing in man's "eternal soul" hence "eternal conscious torment" instead of death in the lake of fire, "going to heaven after we die" instead of being resurrected and ruling and reigning in Christ's Kingdom to bring others to salvation and so forth as that evil eye saw and put into one's body.
To conclude, GotQuestions has this filter of paganism. But be patient with these Christians. They are learning yet. Now, don't get me started on their stance on Young Earth Creationism. The scientists got that right that space and the Earth is really as old as they say, but that was the previous Earth age. God "terraformed" this planet and the rib of Eve was His version of "cloning" for His new creation, Adam, so that no laws of science, which God made and won't break, were broken. This was for this present Earth age. The Bible clearly says there's yet another Earth age. I hate these 6000 year-old "universers" that say stupid stuff like God made the light from billions of years ago magically form in mid-travel to look that way. ???? Might as well then be a flat earther. My avatar buddy, Sir Isaac Newton, BTW believed each creative "day" was simply longer, also a valid point that can work by itself or in conjunctino with an earlier Earth age.
