The "morality" of man vs. the morality of God
If you want to know why Donald Trump is the President of these United States, look no further than this: A certain celebrity actress and singer is being blasted by feminists for her vegan diet. Yes: She is being blasted by feminists for embracing a Leftist cause. This kind of insane politically correct nonsense is what many Trump voters rebelled against in 2016.
It also underscores a critical lesson about morality: God's moral standards are infinitely superior to man's moral standards. The biggest reason for this is that God's moral standards as seen in the Bible are eternal and unchanging. Man's moral standards morph and change based on feelings and whims. No matter what someone does, there will always be some Leftist somewhere who is offended and claims it promotes discrimination, or something.
It used to be that Leftists (especially environmentalists) loved veganism. It was a "cruelty free" diet that not only avoided directly causing the death of an animal to consume its flesh, but did not "oppress" animals by taking their milk. It was the height of "woke" progressiveness to embrace a "cruelty free" lifestyle... until about five minutes ago. Now it promotes imperialism and discrimination. But do not worry! In another five minutes it will be moral again. We cannot promise anything five minutes after that.
And thus we see the problem: Nobody knows what is right or wrong. In five minutes, something that is loving and wonderful right now will not only be bad, it will be retroactively bad. Contrast this with the Word of God, which sets forth the standard of morality for all time. Those who want to obey God have no difficulty knowing exactly what the standard is. With man's morality, we cannot obey constantly shifting standards. With God's morality, we at least know what the standard is, and that it will never change. God will not praise us today and damn us tomorrow for doing the exact same thing.
But what about all of those Christian sinners, you might say. The fact that people fail to uphold a standard does not mean the standard is bad. Think of it like speed limits: Most people break the limits and drive faster than the posted speed. But does that mean we should have no limits, so people are permitted to drive 100 miles per hour through a suburban neighborhood? Do I really need to answer that rhetorical question?
Of course, even though the standard is clear, we cannot hold to God's standard. We will fail, and we will sin. We cannot come into God's presence because we all broke His law and we are unclean. But even then a loving God provides a way of escape: The shed blood of His only Son, spilled for our benefit. We are pardoned so that sin will not condemn, and then we are given the Holy Spirit to sanctify us so that sin will not rule. Eventually, we will be glorified so that sin will not be.
