Was the law ever God's first choice for mankind? ..................... I don't think so. Yes God brought the law, but He always had planned on grace, through the person of Jesus. After all Jesus was the lamb slain before the foundations of the world. And no, the law wasn't plan B, because grace wasn't working. No the law came because, well basically the Israelites asked for it. God knew this beforehand. He knows everything and yet still our failures can't mess up His plan. He uses even our mistakes, our unbelieving hearts to still work together for good. He can turn everything and use it to point to Jesus!! Isn't that awesome!!
I just love Hebrews 10, I find it gets richer and richer every time I am referred back to it! Check out verse 8 in particular and tell me if you think God wanted to bring the law because that was His ultimate plan for us!!
