In Mark 12:25 Jesus says: "For when they shall rise from the dead, they neither marry nor are given in marriage; but are as the angels in heaven."
In Matthew 19:12 Jesus says: "there be eunuchs, which have made themselves eunuchs for the kingdom of heaven's sake."
Psalm 51:5 says: "Behold, I was shapen in iniquity; and in sin did my mother concieve me."
I Corinthians 7:8-9 says: "I say therefore to the unmarried and the widows, It is good for them if they abide even as I . But if they cannot contain, let them marry: for it is better to marry than to burn."
So, I would be curious to know what people think of all of this. Maybe we will be so euphoric in heaven that sex never even crosses our minds. I seriously doubt that any new children will be born in heaven- but who knows.
