People love the lies of Satan that disregard the Laws, Satan has made the rules, laws and commandments an enemy, and the lusts of the flesh are quick to believe these lies.We love simple formulas. We have had 2,000 yrs to come up with our unique take on the dissection of the Law of Moses. We divide those laws into clear categories that fit our concepts of morality and religion. We like the clarity of the 10 commandments, but we deny their implications and applications. The same law that says you must not commit adultery, which we accept, also says that a women caught in adultery must be put to death. Just an example of the lip service we make that make the 10 Commandments into the 10 principles. When the 10 Commandments says "make no graven images" we laugh. Our world is 90% graven images. When the 10 commandments requires to Keep the Sabbath day holy, that is our recreation and party day. The commandment is to have no other god before me, but if we examine our checkbooks we find that there dozens of gods in front of God (where your money is there will be your heart also. A man cannot love God and money etc).
We tend to find ways, interpretations, rationalizations, creeds and dogmas that all have one function, relieve us from responsibility to God. We do not have to obey God. That was the old law. All we need now is what we call "faith." Then we can and do live exactly like we did "pre-salvation." The Old Law demonstrated the gap between how we chose to live and the way God wants us to live. We are thrilled it no longer applies, because we no longer have anything that requires any unique behavior, only a unique way of thinking we call faith. We have further inoculated our spiritual lives with the holy medicine that says even attempting to live in obedience is a form of false religion because it involves "works." The old law taught us obedience was God's chosen path to Him. Our New Law says obedience is the enemy of "true faith." Obedience might come as a result of faith or not. It does not matter because it has nothing to do with our "salvation." We once agreed to a 60 second pulpit prayer and in return we have a guarantee of heaven..... obedience is sooo Old Testament
People are good at making excuses, justifying their actions.
God is merciful and loving but He does not lower His perfect standard of righteousness.
Salvation was the perfect plan to combine justice and mercy.
The moral law was not removed yet God saved us from it by paying the penalty for us. Mercy and Justice.
If He removed or changed or substituted the law so we no longer need to obey it then the standard of righteousness has been changed.
