I'll start with Genesis 1 at verse 24.
"24 And God saith, `Let the earth bring forth the living creature after its kind".
Ok how ?
"28 And God blesseth them, and God saith to them, `Be fruitful, and multiply, and fill the earth".
So God had it so all these creatures brought forth to produce after their kind.
They were given the ability to do so as the scripture says "and it is so".
To not do so is to be disobedient.
We go further in Genesis to chapter 38 about a man's disobedience.
In verse 8, "And Judah saith to Onan, `Go in unto the wife of thy brother, and marry her, and raise up seed to thy brother;'
9 and Onan knoweth that the seed is not [reckoned] his; and it hath come to pass, if he hath gone in unto his brother's wife, that he hath destroyed [it] to the earth, so as not to give seed to his brother;
10 and that which he hath done is evil in the eyes of Jehovah, and He putteth him also to death."
Put the death what he done. It was evil.
Like those who are doing what's evil in Romans 1.
"28 And, according as they did not approve of having God in knowledge, God gave them up to a disapproved mind, to do the things not seemly;
29 having been filled with all unrighteousness, whoredom, wickedness, covetousness, malice; full of envy, murder, strife, deceit, evil dispositions; whisperers,
30 evil-speakers, God-haters, insulting, proud, boasters, inventors of evil things".
This brings out the wrath of God. Of course this likewise equates to death.
"32 who the righteous judgment of God having known -- that those practising such things are worthy of death -- not only do them, but also have delight with those practising them."
Now what do all these passages have in common?
How can they be tied in line upon line?
Good questions, I'm glad they were asked.
Starting from Genesis through Romans, the context concerns the male , female, male and female, the male and female.
The book of Genesis chapter 1 I provided talks about male and female. Chapter 38 of that book, mentions a man which is a male and a woman which was the female the male was supposed to go in unto or into.
The book of Romans, likewise, the male and female.
The second or next line, the evil that was done which connects Romans and Genesis 38 which we know Genesis 1 sets the standard for those two accounts.
See, why is it evil? It's because it's unrighteous. Why is it unrighteous?
It's ungodly, it's not of God, not approved of God. What's approved of God is disapproved by those that meets God's disapproval.
God gave them up to a disapproved mind.
See we start with God telling the male to be fruitful and multiply. Being disobedient to that are those leaving the use , changing the use of themselves as mentioned of the males and females in Romans 1.
Likewise in Genesis 38 the man was disobedient to the same cause.
So by keeping the use , staying with the use of the male and female, the male and female is obedient to being fruitful , multiplying.
In turn which would cut out oral sex, withdrawal and any other sex act used to serve the creature, not the Creator.
You can't serve the Creator denying Him through works at once. Can't serve two masters.
Now the Bible gives no ground for unmarried folk so the only ones justified to be fruitful are the married male and female as indicated in Genesis.
