In many places in the Bible, God destroys nations because of their moral decay. God has spared individuals from the destruction though because of their unwillingness to also become part of the moral decay. Look at Lot being saved from Sodom because Lot was an upstanding individual.
Ezekiel 9:1 Then I heard God shout, “Come here, you men who are going to punish the city. Bring your weapons with you.” 2 At once six men came from the outer north gate of the Temple, each one carrying a weapon. With them was a man dressed in linen clothes, carrying something to write with. They all came and stood by the bronze altar. 3 Then the dazzling light of the presence of the God of Israel rose up from the winged creatures where it had been, and moved to the entrance of the Temple. The Lord called to the man dressed in linen, 4 “Go through the whole city of Jerusalem and put a mark on the forehead of everyone who is distressed and troubled because of all the disgusting things being done in the city.” 5 And I heard God say to the other men, “Follow him through the city and kill. Spare no one; have mercy on no one. 6 Kill the old men, young men, young women, mothers, and children. But don’t touch anyone who has the mark on his forehead. Start here at my Temple.”
There was a point in Israel’s time where the Israelites turned from God and did absolutely awful things. God had Israel conquered by a foreign nation and great suffering passed. But you see here that God spared some. The people who were concerned with their nation’s moral decay were spared. This gives us great hope. Because even if we feel our nation is going through problems such as aborition or gay marriage, individuals will still be spared from God’s anger if it does come upon us. We’re supposed to be concerned with our nation and what other people are doing, but firstly, we should be concerned about ourselves and our own moral conduct.
Matthew 7:1 “Do not judge others, so that God will not judge you, 2 for God will judge you in the same way you judge others, and he will apply to you the same rules you apply to others. 3 Why, then, do you look at the speck in your brother’s eye and pay no attention to the log in your own eye? 4 How dare you say to your brother, “Please, let me take that speck out of your eye,’ when you have a log in your own eye? 5 You hypocrite! First take the log out of your own eye, and then you will be able to see clearly to take the speck out of your brother’s eye.
If you refine yourself to be morally spotless in every way, and you feel confident that you repented of sinning, maybe you can start telling others to stop sinning. Personally, I fall into sin and temptation from time and again. Sometimes I do stuff that I am not sure if it is sin or not. Some may take the moral high road and pull the speck out of their brother’s eye, but that isn’t for me. I know that if I fall that I’ll need forgiveness. If I judged another man harshly, God will judge me harshly when I fall to show me the error of my ways.
Still there is no excuse to turn a blind eye to the evils around us. If we see something wrong or corrupt, we should speak up about it. We have the truth. And the power of the truth is being known and coming out to the light. It is the people who walk in darkness that don’t want their deeds to be uncovered. Sometimes this is a scale to weigh if what we’re doing is a sin. If we’d want people to know what we’re doing, it typically isn’t a sin. It doesn’t work for everything, but it does for a lot of things.
Pr 14:10 Your joy is your own; your bitterness is your own. No one can share them with you.
In the end though, we’re each judged individually. God may take in some environmental factors into how you learned bad behavior, but I wouldn’t use them as a crutch. We’re supposed to stand up and be as righteous as possible for there is a time when God will credit it to our favor. Sure, when we were going around as sinners(if this applies to you), we may have made mistakes. But when we were born again and repented of sin, we should be walking a better path. Our rewards will be individual, but even so, it is good to concern yourself with your nation’s struggles because having concern for your nation can count toward your own individual credit. God works that way! And thanks be to God that he does.
