The point is noone can be as good as God. Only God is sinless and compared to Him, we fall very, very short no matter how hard we try.
Jeremiah 17:9 “The heart is deceitful above all things, and desperately wicked: who can know it?”
Isaiah 64:6-7 “All of us have become like one who is unclean,and all our righteous acts are like filthy rags; we all shrivel up like a leaf, and like the wind our sins sweep us away. No one calls on your name or strives to lay hold of you; for you have hidden your face from us and have given us over to our sins.”
1 Samuel 2:2 “There is none holy as the LORD: for there is none beside thee: neither is there any rock like our God.”
Isaiah 53:6 “All of us, like sheep, have strayed away. We have left God’s paths to follow our own. Yet the LORD laid on him the sins of us all.”
Yet another shining example of Christianity’s ripping-off of the Hebrew Scriptures to fit its theology.
