in order to be in the 'body of Christ', a 'woman and a man' must behave in the prescribed manner -
the original Commandment was to 'be fruitful and multiply', but if this is done in an 'un-godly' manner,
the children will be (corrupt-un-clean) -
1COR. 7:14.
For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband:
else were your children unclean; but now are they holy.
to bear 'Godly children is the 'point', to be fruitful and multiply =
when we are in 'the Body of Christ', it's just explaining of the Commandment, this is what
has to be done NOW, 'if it is possible for one to bear children'...
(sin is passed-on), as it is written:
1COR. 15:22.
For as in Adam all die, even so in Christ shall all be made alive.
