There are times in reading the Old Testament where God is described very much as the Tribal God, and Israel is God's Tribe. There is nothing soft, or gentle about this image of God. There are also times in the Old Testament where God is painted as the universal sovereign. No image we paint of God is all encompassing or sufficient.
Psalm 137:8-9
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!
Proverbs 8:22-31
The Lord created me at the beginning of his work, the first of his acts of long ago. Ages ago I was set up, at the first, before the beginning of the earth. When there were no depths I was brought forth, when there were no springs abounding with water. Before the mountains had been shaped, before the hills, I was brought forth— when he had not yet made earth and fields, or the world’s first bits of soil. When he established the heavens, I was there, when he drew a circle on the face of the deep, when he made firm the skies above, when he established the fountains of the deep, when he assigned to the sea its limit, so that the waters might not transgress his command,when he marked out the foundations of the earth, then I was beside him, like a master worker; and I was daily his delight, rejoicing before him always, rejoicing in his inhabited world and delighting in the human race.
The Old Testament is not monochrome, and it does not paint a monochrome picture of God. Of course there have been passages here that seem to suggest that violence against children is OK, which I would want to assure you is not the message of the Gospel, or of the Bible. Michael W Smith in authoring the lyrics of 'Our God is an awesome God' whilst it is a lot of joy to sing with such a great tune, is really only a half step away in the image of God that is presented.
Reverence and Awe are part of the abiding marks of our approach to God. Sometimes this is called the fear of the Lord, but I sense the danger of that expression is that we paint a picture of a scary God and in a sense paint God as a Monster.
So I guess about verse 23, I read it in context, and I see it as not the whole picture. If it was the whole picture it would be very sad.
Job 38:1-7
Then the Lord answered Job out of the whirlwind: ‘Who is this that darkens counsel by words without knowledge? Gird up your loins like a man, I will question you, and you shall declare to me.
‘Where were you when I laid the foundation of the earth? Tell me, if you have understanding. Who determined its measurements—surely you know! Or who stretched the line upon it? On what were its bases sunk, or who laid its cornerstone when the morning stars sang together and all the heavenly beings shouted for joy?
