Who are the 144,000?

1. They have never told a lie (they therefore cannot have learned to speak - we ALL have lied)
2. They are virgins (they are too young / unmarried - Jewish tradition tends toward young marriages)
3. They follow Jesus everywhere he goes (Matthew 19:14)
4. They are of the 12 tribes
5. They sing a song no-one else can learn
6. They are firstfruits to God and the Lamb (firstfruits = saplings = green = already offered up and waved)

They are YOUNG... VERY YOUNG.
They fit better the description for the toddlers killed in Egypt and the toddlers killed when Jesus had to flee to Egypt.
I fail to see how they will appear after the rapture.
Please, someone prove me wrong using scripture.
