When are you ready for marriage?

To answer this I ask another question; "Are you a wall or a door"?

In the Bible this question is posed, Song of Songs 8:8 the girls brothers ask, (as a matter of background the girls father is evidently not around for some reason or another, hence the older brothers are responsible for the household);

"We have a little sister, And she has no breasts. What shall we do for our sister In the day when she is spoken for?"

Basically they are asking how they will come to an answer when someone comes to ask for their sister's hand in marriage.
Here's how they answer;

"If she is a wall, We will build upon her A battlement of silver; And if she is a door, We will enclose her With boards of cedar."

Here these men answer by saying that if their sister is mature enough to have control over sexual desire and to be defensive against boys who may chance their arm (or hand), if she is not sexually promiscuous but is sexually pure and holds strong morals then they will encourage her and support her, giving a blessing when the time comes.

But if she is a door, meaning if men can just go in and out of her like a door banging in the wind, if she is promiscuous like a dog in heat then they will lock her in her room and board it up and prevent her from getting to guys or men getting to her.

I love this girls answer;
"I am a wall, And my breasts like towers;"

She declares that she is a wall, guys don't cum and go as they please (forgive the pun), and she goes further by saying that her breasts are like towers, not meaning the size but that they are well respected and well defended; if a guy reaches his hand to feel them she considers it an attack and defends against it.

So the Biblical directive of when one is ready for marriage is to ask if that person is a wall or a door, if they are sexually active, promiscuous and cannot control their lust or if they have self control, honouring God and able to keep themselves from temptation as well as to defend against such attacks on something so precious.
