The following is a reply to someone who asked me some questions regarding the afterlife.
I believe the Scriptures are clear that when a person dies they either go directly to heaven or directly to hell, and there they await resurrection and judgment (2 Kings 2:11, Luke 16:19-31, 2 Corinthians 5:6-8, Philippians 1:23, Revelation 6:9-11, etc). I reject the idea of "soul sleep", the notion that when men die they are like those who are asleep and thus remain unconcious until the resurrection. This is based on an erroneous understanding of the usage of the word "asleep" in the Bible, which describes the dead in Christ (for example, John 11:11, 1 Thess. 4:13). All the Scripture means by the word "asleep" is that for the saints, death has lost its sting and that death is not permanent. The word isn't talking about the consciousness of the dead, but the non-threatening nature of death for those who are in Christ, as well as its impermanence.
Someone might ask why people go to heaven or hell before the judgment day has even judged them, but we must remember that people are already under the wrath of God if they don't believe in Jesus, and if they do believe they have already been delivered from it (John 3:36). God's judgment has already been decided, and this is not the issue of judgment day. Judgment day has to do with the public manifestation of judgment, when everyone shall see the truth about the state of men. Thus we shall all be resurrected to be judged publicly.
But we must also remember that the Bible speaks about two resurrections: the resurrection of the righteous and the resurrection of the unrighteous (Acts 24:15, especially Revelation 20). The first resurrection, which is for the righteous, takes place the day Jesus Christ returns (see also 1 Thess. 4:16), and we shall be resurrected to join the Lord in His glory. It will be a public glorification of the saints with Christ (Colossians 3:4). There is no fear in this judgment, for it is without any condemnation whatsoever. But the opposite is the case with the second resurrection of the unrighteous, which takes place after the millennium (the thousand year reign of Christ). All the remaining dead will be raised and judged according to their works, and they will therefore be sent to the lake of fire forever. There is nothing but condemnation. We definitely don't want to have a part in that - to avoid it is to believe in Jesus Christ now so to be justified through faith in Him apart from our works altogether, and to receive the free gift of eternal life!
I believe your baby is in heaven and you'll see her either the day you die or before that if Jesus Christ returns. That was David's beautiful hope when he lost his son.
Hope this answers some of your questions.
Sincerely, your brother in Christ,
