True. And I'm sure that a just and loving God would make sure unrepentant sexual abusers get what they deserve in the end. But what about during the time on Earth? How much intervention there would be from the divine would be questionable. Obviously, He wouldn't be smiting everyone who stole something the moment they stole it. And since Israel eventually declined into moral depravity so badly that He took His protection away, I don't think He was intervening on a daily basis with their lives and how they chose to lead them.
But if we're to believe He wrote the Mosaic Laws, and not some human, then we would see this perfect and just and loving God intervening, if only a little through the act of writing a law, against petty crimes like theft, and intervening not at all with crimes like sexual abuse. And if He didn't tell them not to, and their whole history of laws from every other society that came before them said such actions were okay, they could almost claim ignorance that they didn't know they weren't supposed to.
There were a lot of laws that held women to different standards when it came to sexuality than men, so why would they assume there shouldn't be a double standard in other aspects as they see fit?
I don't see the lack of laws as evidence of God having a poor character, or that He doesn't exist. I see it as evidence that there was a clear lack of divine influence that went into the writing of those laws, nothing more.
35 Then one of them, which was a lawyer, asked him a question, tempting him, and saying,
36 Master, which is the great commandment in the law?
37 Jesus said unto him,
Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
38 This is the first and great commandment.
39 And the second is like unto it,
Thou shalt love thy neighbour as thyself.
40 On these two commandments hang all the law and the prophets.
And these character attributes are further defined by the Apostle Paul...
1. Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal.
2 And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
3 And though I bestow all my goods to feed the poor, and though I give my body to be burned, and have not charity, it profiteth me nothing.
4 Charity suffereth long, and is kind; charity envieth not; charity vaunteth not itself, is not puffed up,
5 Doth not behave itself unseemly, seeketh not her own, is not easily provoked, thinketh no evil;
6 Rejoiceth not in iniquity, but rejoiceth in the truth;
7 Beareth all things, believeth all things, hopeth all things, endureth all things.
8 Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away.
9 For we know in part, and we prophesy in part.
10 But when that which is perfect is come, then that which is in part shall be done away.
11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things.
12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
13 And now abideth faith, hope, charity, these three; but the greatest of these is charity. - 1 Corinthians 13
If mankind gets these spiritual attributes inside his character he will have no need for laws.
