8 Bible Verses about Sins Of Omission

Then the Lord spoke to Moses, saying, “Moreover, you shall say to the children of Israel,

‘Any Israelite or any stranger residing in Israel who gives any of his children to Molech (the god of the Ammonites) [as a human sacrifice] shall most certainly be put to death; the people of the land shall stone him with stones. I will also set My face against that man [opposing him, withdrawing My protection from him] and will cut him off from his people [excluding him from the atonement made for them], because he has given some of his children to Molech, so as to defile My sanctuary and profane My holy name. read more.
If the people of the land should ever tolerate that man when he gives any of his children [as a burnt offering] to Molech, and fail to put him to death [as My law requires], then I shall set My face against that man and against his [extended] family, and I will cut off from their people both him and all who follow him in playing the prostitute (commit apostasy) with Molech.

Rescue those who are being taken away to death,
And those who stagger to the slaughter, Oh hold them back [from their doom]!

For if anyone only listens to the word without obeying it, he is like a man who looks very carefully at his natural face in a mirror; for once he has looked at himself and gone away, he immediately forgets what he looked like. read more.
But he who looks carefully into the perfect law, the law of liberty, and faithfully abides by it, not having become a [careless] listener who forgets but an active doer [who obeys], he will be blessed and favored by God in what he does [in his life of obedience].

So any person who knows what is right to do but does not do it, to him it is sin.

“Woe to you, [self-righteous] scribes and Pharisees, hypocrites! For you give a tenth (tithe) of your mint and dill and cumin [focusing on minor matters], and have neglected the weightier [more important moral and spiritual] provisions of the Law: justice and mercy and faithfulness; but these are the [primary] things you ought to have done without neglecting the others.

Then He will reply to them, ‘I assure you and most solemnly say to you, to the extent that you did not do it for one of the least of these [my followers], you did not do it for Me.’

“But woe (judgment is coming) to you Pharisees, because you [self-righteously] tithe mint and rue and every [little] garden herb [tending to all the minutiae], and yet disregard and neglect justice and the love of God; but these are the things you should have done, without neglecting the others.

And that servant who knew his master’s will, and yet did not get ready or act in accord with his will, will be beaten with many lashes [of the whip],
