The Bible is not only a religious document; it is one of the oldest historical records of the way that previous civilizations behaved. Values, morals, and societal norms have changed throughout history. Although some of the faithful might overlook these behaviors these days, they were once forbidden according to the written word of God.

Trimming the edges of one’s beard is talked about as forbidden in Leviticus 19:27. Although it’s commonplace in today’s society, and, in some instances, expected as a sign of respect, at one time, it was not a grooming ritual that was practiced or even allowed.

Love them or hate them, people have the option to get tattoos or not. According to Leviticus 19:28, however, it’s sinful to mark or tattoo the body. Because self-expression was considered hedonistic, tattoos were not allowed way back, but are becoming widely popular in the modern age.

Letting Your Credit Card Balance Revolve

Nowadays, to get a home, buy a car, or even use a credit card, you are likely charged interest. In the time of the Bible, however, it was prohibited. According to Exodus 22:25, charging interest on loans is greedy and takes advantage of the unfortunate people in society. 

Enjoying Shellfish

In Leviticus 11:10, it’s said that eating shellfish is an abomination. Now it’s considered a delicacy in many regions around the world. It’s surprising at a time when people had to live off of the land and sea that it would be considered a bad thing.

Wearing Fabrics Made from Different Materials

Whether you’re on the side of fashion where mixed fabrics are okay or not, there was a time when it was considered more than just unstylish. According to Leviticus 19:19, people were forbidden from wearing any clothes that were made from more than one kind of material. If that were the case today, there would be a lot of sinful merchandisers out there. 

Spreading or Engaging in Rumor

Gossip is something that nearly everyone does, but it was once considered a sin. Although it’s a common form of social interaction, there was a time when talking about others, other than yourself, was sinful. According to Leviticus 19:16, there’s an importance placed on the integrity of one’s speech, which includes speaking ill of others. 

Working On Sunday

Chick-fil-A and dealerships are saintly establishments according to the Bible because they uphold the Sabbath. According to Exodus 20:8-11, the Sabbath is a holy day and everyone should refrain from working for the full 24 hours. The Sabbath has traditionally been seen as a time of devotion and rest for humankind.

Pork On Your Plate

According to Matthew 19:9, divorce is only granted in situations where there has been infidelity in the marriage. At a time when statistics tell us that 40%-50% of all marriages don’t make it, there are a lot of people not following the Bible. The Bible places a high regard on the sanctity of faithfulness and marriage.

According to the Bible, jealousy is a sin and an emotion that’s considered unnatural. The Bible believes that everyone should love one another. Galatians 5:19-21 preaches the importance of gratitude and contentment over jealousy.

Drinking Alcohol Excessively

Drunkenness is seen as a sin in the Bible, in Ephesians 5:18, where sobriety and self-control are virtues. While the Bible does not say that drinking alcohol is sinful, it does warn against excessively drinking it. There is a recognition that those who do might not be as guided by being upright and proper.

According to Proverbs 16:18, pride is the catalyst for destruction. Arrogance is seen as sinful and the beginning of the end of harmony. The Bible also teaches against the dangers of being self-important and promotes self-awareness and humility over being self-promoting.

Lustful Thoughts and Actions

Many cultures and religions believe that lustful thoughts and actions are sinful. Matthew 5:28 talks about thoughts of adultery being an act against God. He then talks about lustful thoughts about someone else’s spouse to be infidelity of the mind. So not only are lustful actions outside of marriage sinful but so too are thoughts about it.

James 4:13-14 talks about the sin of being boastful about future plans. James speaks of humility about the fact that life is unpredictable and fleeting. Taking any day for granted and not recognizing that it could be your last is a sin. James’ passage reminds us that talking about the future instead of enjoying the here and now might be wasted energy.

You are supposed to do to others as they would have done to you, and anger is not part of that equation. According to Matthew 5:22, anger is one of the most serious offenses that you can commit against your brother. He spoke of reconciliation, forgiveness, and seeking peace as the only righteous way to exist. 

Speaking Badly of Others

It’s considered sinful to rise against a ruler in the Bible because it’s seen as a disrespect for authority. According to Exodus 22:28, following the lead of a ruler is the only way to maintain stability in a community. So speaking against or ill of a leader is considered a sin.

According to Colossians 3:9, honesty is a virtue. If a person doesn’t have integrity of speech, a community will not survive. The Bible warns against the sins of lying and being dishonest.

Being Vengeful

Holding grudges and seeking revenge are both sinful acts according to Leviticus 19:18. The Bible preaches instead that one should be forgiving and seek reconciliation instead of retaliation. The Bible preaches that letting go of desires for revenge is the only way to keep peace in a community.

Dishonoring Your Parents

In the Bible, it’s considered sinful to not honor one’s parents. According to Exodus 20:12, being respectful is a foundational principle of gratitude and respect. Although there tends to be a trend toward generational disrespect, the Bible valued it thousands of years ago.

Gluttony is a prevalent sin in the Bible because it’s the catalyst for poverty and destitution. The Bible preaches against overindulgence and for moderation in all things. Self-control and temperance are two things that are emulated throughout the Bible but especially in Proverbs 23:20-21.

Galatians 5:26 speaks of envy as being destructive to a community’s harmony and wellbeing. The Bible promotes contentment and personal growth over wishing you had what someone else does.

Being Unforgiving

Throughout, the Bible highlights the necessity of forgiving others. Matthew 6:15 teaches that healing is necessary in relationships and the only way to foster healthy ones is by giving others mercy and grace. Those two things cannot happen unless you forgive someone. 

Sowing Discord

Sowing discord is not something that we speak of in the modern day. In Proverbs 6:16-19, it’s a destructive behavior that’s condemned. Sowing discord means stirring things up between others and creating a state of discord. The Bible promotes love and forgiveness, leading to harmony not discord.

The Bible was written centuries ago but still has practical use today. Although not many of us follow it strictly and to the letter, there are actions and behaviors that were once considered sinful that are not now.
