"The servant who knows the master's will and does not get ready or does not do what tthe master wants will be beaten with many blows. But the one who does not know and does things deserving punishment will be beaten with few blows. From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked" Luke 12:47-48
We must learn to take sin as seriously as God does. One reason for all the sacrifice and continual purification rituals in the Old Testament was to show the prople how far they were from God's holiness. The purpose of negative consequences is to teach us to see sin the way God does and hate it as He does. When we commit a sin in ignorance, God brings consequences to help us learn. Once we know better, He expects us to do better. We do the same with our children. Simply because a four-year-old had not been specifically told not to squish the bananas in the store does not mean Mon is fine with it. There will be consequences, even if he can claim ignorance of the specific rule, and he will be told clearly that squishing bananas will not be tolerated again. Of course, his consequences the first time may not be severe as they are likely to be if Mom catches him squishing more bananas after being instructed not to.
God is a father, and He loves His children. He does not delight in punishing us but in conforming us into the image of His Son. He does not tolerate excuses, including the excuse of ignorance; rather, He gives us opportunities to learn from our consequences so that we make better choices. He knows what each of us has been given and holds us responsible for what we do with it. We've all committed sins in ignorance, but God does not leave us ignoranrt. He has given us His Word to show us how to live, and He expects us to apply it to our lives and seek holiness, "without which no one will see the Lord".
