We should be careful not to downplay the seriousness of sin because it offends our wrathful God, and believers need to live in the light
Some people consider sin no big deal and think breaking biblical rules won’t have any effect on them. But they are actually deriding God with their attitude. What’s more, they have fallen victim to the enemy’s deception that it’s possible to get away with wrongdoing. For this reason, right before teaching the principle of reaping what is sown, Paul tells the Galatians, “God is not mocked” (Gal. 6:7).
The truth is, what we or anyone else thinks about sin is not the issue. All that matters is what God thinks, and He has made His views very clear in the Scriptures. So if we trivialize our sins, it’s an indication we don’t understand how holy and just the Father is. To emphasize the seriousness of sin, Paul lists ways we offend the Lord with our motives, impure character, words, idolatries, and actions. And in verse 6 of today’s passage, he warns, “For because of these things the wrath of God comes upon the sons of disobedience.”
As believers, we need to remember how offensive transgression is to God. Although we’ve been saved from His wrath, we cannot sin as we please and claim it’s all covered by grace. Our aim should be to live as children of light, not darkness
