The capacity to make life is in the male sperm and the female egg is it not? If you destroy all sperm and all eggs how will any life come into existence?I fail to see how some contraception is killing life.
The idea of contraception is to avoid the formation of life... which do you think is worse...to avoid life or to abort life?There is some contraception that kills life but not all.
the scripture does not say that...it says he spilled his seed because he knew that they would not count as his own...Onan was using his brother's wife for pleasure.
the scripture does not say that either... it says God was displeased because Onan spilled his seed...here it is in black and white...Not bringing up a Godly line for the messiah to come is what displeased God.
9 And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother's wife, that he spilled it on the ground, lest that he should give seed to his brother.
10 And the thing which he did displeased the Lord: wherefore he slew him also.
