Q. What happens to Christians when we die? Do we wait for the return of Christ before we are taken to heaven? This scripture is what prompted me to ask the question: “The Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever.”
Also, is it by default that as Christians we would be spared from hell if we believe in our God and that Jesus died for our sins and we pray for forgiveness and forgive the others? Or would we be vetted further?
In answer to your first question, I’d invite you to read the following post, which I wrote in response to a different but similar question and which I believe will address your concern:
In that post I say that “all things considered, my overall sense from the Bible is that the soul of a believer does pass directly and consciously into the presence of God upon death.” However, I acknowledge that this is “a question on which people of good will who are equally committed to the authority and inspiration of the Scriptures have long disagreed. So we each need to be ‘fully convinced in our own minds’ but respectful of the other position.”
In answer to your second question, there’s another post on this blog that I can recommend. It, too, was written in response to a different but similar question, and I think it will speak to your own question:
In that post I conclude that “if we claim to have been saved by trusting and believing in what Jesus did for us, we should reasonably expect that salvation to manifest itself in ‘works,’ not things we do to earn or secure our salvation, but things that flow naturally from it.” We will not necessarily be “vetted” by such things, but they do give us the opportunity to “vet” ourselves and confirm that the fruits of salvation are appearing in our lives.
I share some similar thoughts in this further post:
There I observe: “I think the simplest way to summarize the New Testament position on this subject is to explain that while it doesn’t teach we are saved by works, it does teach we are saved for works. That is, God has saved us so that we will be able to live in the way He has designed.” Once again, seeing these results in our lives can give us greater assurance of salvation, which is what I believe you are asking about.
I hope these leads are helpful to you.
