In no particular order of gravitas.
(1) The story of Gods faithful obedient servant Job.
With having unlimited power over everything in the universe, God says to Satan -
"And he still maintains his integrity, though you incited me against him to ruin him without any reason.” Job 2:3
The story of Job has to be among the saddest example of God's Love and Grace in these "god breathed" scriptures. God sanctions the death of all of Jobs 10 children but as we can see above, God is not happy having to do this "without any reason". One can become quite weepy once we realise that it is Gods love and grace that is clearly shining through showing us how cheap life really is to him.
(2) The right to worship by the love and grace of God at any cost.
O daughter Babylon, you devastator! Happy shall they be who pay you back what you have done to us! Happy shall they be who take your little ones and dash them against the rock!" Psalm 137:8–9 .
This appears to be a ` deary me never mind ' comment from God who was merely saying how regrettable it is that even babies become collateral damage during conflict. But is also saying those that believe in him "should be happy-or blessed — to kill innocent babies if they keep you from worshiping him. How lovingly gracious of god to put their concerns of worship & his own vanity before those of innocent babies.
(3) Cannibalism enforced by God.
"And if ye will not for all this hearken unto me, but walk contrary unto me; Then I will walk contrary unto you also in fury; and I, even I, will chastise you seven times for your sins. And ye shall eat the flesh of your sons, and the flesh of your daughters shall ye eat." Leviticus 26:27–29
This appears to be one of those - `you keep forgetting me, what about me' -tantrums from God. He is feeling a bit left out of the picture so, as punishment, he threatens his them "chosen people, Israel" that he will cause them to eat their own children. The love and grace that God shows in this verse is enough to bring tears to ones eyes.
(4) The vow of a General and a virgin for God .
"And[general] Jephthah made a vow to the Lord: 'If you give the Ammonites into my hands, whatever comes out of the door of my house to meet me when I return in triumph from the Ammonites will be the Lord's, and I will sacrifice it as a burnt offering.' . . . When Jephthah returned to his home in Mizpah, who should come out to meet him but his daughter, dancing to the sound of timbrels! . . . After the two months, she returned to her father, and he did to her as he had vowed." Judges 11:30–39
This is really a true show of loyalty and devotion to God and a story of how one should keep their promises made to a loving and gracious God . and of course like all biblical stories of gods love grace this virgin wasn't sacrificed for nothing. No. what sprang from this story of loyalty , devotion and obedience was the Israelite tradition that each year the young women of Israel go out for four days to commemorate the daughter of Jephthah the Gileadite. I bet this young - dead - fried to a crisp - virgin is happy with her sainthood. God does work in mysterious ways.
(5) Killed for not keeping it in the family and rewarded by God.
"Just then one of the Israelites came and brought a Midianite woman into his family, in the sight of Moses and in the sight of the whole congregation of the Israelites. When Phinehas, son of Eleazar, son of Aaron the priest, saw it, he got up and left the congregation. Taking a spear in his hand, he went after the Israelite man into the tent, and pierced the two of them, the Israelite and the woman, through the belly. So the plague was stopped among the people of Israel.
The Lord spoke to Moses, saying: 'Phinehas, son of Eleazar, son of Aaron the priest, has turned back my wrath from the Israelites by manifesting such zeal among them on my behalf that in my jealousy I did not consume the Israelites. Therefore say, "I hereby grant him my covenant of peace. It shall be for him and for his descendants after him a covenant of perpetual priesthood, because he was zealous for his God, and made atonement for the Israelites.' '" Numbers 25:6–13
Indeed seems all very racial hatred but once again we see God showing his love and grace by rewarding Phineas with a perpetual priesthood and all the trimming that come with it for keeping his" chosen people" racially pure.
(6) Another display of how cheap human life is to God, in his love and grace.
"See, the day of the Lord is coming — a cruel day, with wrath and fierce anger. . . . I will put an end to the arrogance of the haughty. . . . Their infants will be dashed to pieces before their eyes; their houses will be looted and their wives violated." Isaiah 13:9–16
So again, we can witness another a perfect example of Gods love and grace on display. This of course is because God is such a generous loving and graceful and all powerful god, that he can simply create more children to be "dashed to pieces" and more "wives to be raped". All of gods' love and grace can be so overwhelming at times, it really can.
(7) With Gods love and grace, he extinguishes fetuses of those who do not worship him.
"You shall acknowledge no God but me. . . . You are destroyed, Israel. . . . The people of Samaria must bear their guilt, because they have rebelled against their God. They will fall by the sword; their little ones will be dashed to the ground, their pregnant women ripped open." Hosea 13:4, 9, 16.
Well we can see here that through gods love and grace that he is teaching those unborn fetuses a real lesson in obedience in how to be submissive. And lets hope future fetuses will learn from this lesson delivered with the love and grace by the lord God himself.
