I can only guess what the person means by "Immediate life"? I think the quick answer is NO. But let me mention a few items or common misconceptions people have as to what happens when we die.
Scripture says that after we die, our soul (spirit) immediately appears before God for judgement (Hebrews 9:27). That judgement determines our eternal fate - heaven for the elect, or hell for the reprobate.
Now lets take a more detailed look at this topic, and see what happens to the soul between death and resurrection? What state or mode of existence will it be in?
There is a teaching or belief that when a person dies that his soul just goes to sleep until the time of the future resurrection. In this condition, the person is not aware or conscious of anything. Such a belief is incorrect and very unscriptural. First, a few definitions.
What is man? Man is a composite being consisting of both a material and a spiritual component. Man differs from God and the angels in that we have a material body, while they do not.
The spiritual portion of man (the soul) is what gives life to the body, it is the animating principle of human life.
When does life begin? It begins at conception. When the female egg cell, and the male sperm cell unite in the mother’s womb, the first cell combination (called a Zygote) is formed. At this precise instant, God infuses the soul into the fertilized egg, and a new human being is created.
When does death occur? As life begins by the joining of body and soul, death is the reverse of that process. Death occurs at the separation of body and soul. At that point, the body dies, but the soul does not die. Once created, the soul will exist forever.
In other words, once created, the human person will exist for all eternity. True, our physical bodies will die (temporarily) and then be reunited with our soul at the general resurrection at the end of the world – a glorified body for the elect – a dammed body for the reprobate.
In this life knowledge and information reach the intellect through the medium of our five senses, which tend to inhibit our ability to comprehend spiritual matters. St. Paul talks about this imperfect human condition of ours when he says: “…For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.” 1 Corinthians 13:12.
After death, the soul will be very much awake, and aware of its own true identity. As the soul is now detached from the body, the dampening or inhibiting effect of the body, which it previously exerted upon the soul, is now removed. The question is often asked concerning those who suffer from mental illness. As was just indicated, after death, these people will be free of the inhibiting effect of the body, and their mental faculties will be perfectly normal.
As soon as our soul is separated from our body, we will see ourselves, know ourselves with perfect clarity, and we will remember everything we have ever experienced during this life (including our sins) with startling vividness.
At this point we will see ourselves as God sees us. We will see and know if our loyalty to Christ and his teachings has been true, or if we have allowed ourselves to be seduced by the errant ways and false teachings of the world, and we will know what our eternal fate will be – heaven or hell – and that for all eternity.
This instant is called the particular judgement (Hebrews 9:27), as opposed to the general (social) judgment where everyone will see the perfect justice and mercy of God. (Matthew 25:31-46). Consider the following scripture passages which relate to this discussion.
In Matthew 17:1-8 - The Transfiguration – “…And behold, Moses and Elijah appeared to them, talking with Him…” We see here that Moses and Elijah were both very much alive even though their bodies were dead.
In Luke 16:19-31 - The story of Lazarus and the rich man. We see that after each has died, both were conscious and aware of their situation. Abraham also converses with the rich man in hell.
In 2 Cor. 5:8 “we are of good courage, I say, and prefer rather to be absent from the body and to be at home with the Lord." Here, Paul is telling us that he would rather be outside of his body, "absent from the body", and be at home with the Lord. If soul sleep is a true doctrine, then how is it possible to be at home with the Lord and asleep at the same time?
Revelation 6:9-12 – “And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held. And they cried out with a loud voice, saying: How long, O Lord (holy and true) until you judge and revenge our blood on them that dwell on the earth? And white robes were given to every one of them one; and it was said to them, that they should rest for a little time, till their fellow servants, and their brethren, who are to be slain, even as they were, should be filled up”. Obviously these souls are not asleep if they were “crying out”
In 1 Peter 3:18-20 we see Christ preaching to the spirits who were in prison. Obviously these souls were also not asleep.
So now referring back to the original question and the term "immediate life". I know from personal experience that some Protestants have told me that (they believe) they are going to heaven the minute they die. Their belief is based on a false understanding of the scriptural requirements for salvation.
