Hi Bob,
No one will be saved in this life.
Mat 24:13 "But he that endureth to the end, the same shall be saved."
"Shall be saved," is yet a future event.
Little chilldren will not be in the first resurrection either. You must first be called, to come to know Christ. Then chosen and have your eyes open to the truth, and then remain faithful for the rest of your life.
Rev 17:14 "These will make war with the Lamb, and the Lamb will overcome them, for He is Lord of lords and King of kings; and those who are with Him are called, chosen, and faithful."
The faithful few are those in the first resurrection, this is the elect that will reign and rule with Christ.
Rev 20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that had been beheaded for the testimony of Jesus, and for the word of God, and such as worshipped not the beast, neither his image, and received not the mark upon their forehead and upon their hand; and they lived, and reigned with Christ a thousand years.
These thrones tho symbolic are for the elect to judge the rest of mankind. They along with Christ will be the Lake of fire.
Heb 12:29 for our God is a consuming fire.
1John 3:2 Beloved, we are God's children now, and what we will be has not yet appeared; but we know that when He appears we shall be like Him, because we shall see Him as He is.
In Rev. 20:4 it says "reigned with Christ a thousand years."
This thousand years is symbolic, and means how ever long it takes.
2Peter 3:8 "But forget not this one thing, beloved, that one day is with the Lord as a thousand years, and a thousand years as one day."
This is the second resurrection it is an age where the whole world will be raised and judged. They will give account and be purged and cleansed, according to what is needed to remove all of the fleshly carnal nature. Then they will be taught the truth.
Luke 12:47 And that servant, who knew his lord's will, and made not ready, nor did according to his will, shall be beaten with many stripes;
v. 48 but he that knew not, and did things worthy of stripes, shall be beaten with few stripes. And to whomsoever much is given, of him shall much be required: and to whom they commit much, of him will they ask the more.
Think about the prophets of the OT and John the Baptist, I don't think it will take much for them to be brought into the kingdom. But even they must come to recognize Christ's sacrifice, which came after their deaths. I think that would be the few stripes.
Now there are those who have hardened hearts to the point it will take a long time and many stripes to purge and cleanse them. But this is to last an age of time, and 2 peter gave a day to a thousand years, so that should be a good judge of how long it will last.
This is what I have come to understand about the first and second resurrections.
mercy, peace, and love
