Poor and needy: Helping the poor is linked to blessing for the believer, because when a believer gives unto the poor, it’s as if he/she gives unto the Lord, and the Lord is the one who blesses them (Proverbs 19:17). We should take after Jesus and His Disciples in their giving to the poor regularly on ministry trips (John 13:29). We do not have this life to be served upon, but we must, as believers just as Jesus did, to serve one another (Mark 10:45).
Pornography and sexual immorality: The Bible speaks completely against all forms of sexual immorality including adultery, fornication, pornography, homosexuality, orgies, etc. Those who look at a woman with lustful intent have committed adultery in his heart (Matthew 5:27-30). Pornography is addictive (1 Corinthians 6:12; 2 Peter 2:19) and damaging (Proverbs 6:25-28; Ezekiel 20:30; Ephesians 4:19). It is unacceptable, for those who practice sexual immorality do not inherit the Kingdom of God (1 Corinthians 6:9-10). People who want to be saved but choose to be in a sexually immoral lifestyle instead (Revelation 9:21-22). Of course, Revelation 17 talks about harlotry and sexual immorality. Revelation 21:8 and 22:15 details what will happen to the sexually immoral. Believers are instructed to consider the members of the earthly body as dead to immorality, impurity, passion, evil desire, and greed, which amounts to idolatry (Colossians 3:5). Sinning sexually is committing sin against your own body (1 Corinthians 6:18). Homosexuality is sin (Leviticus 18:22; Romans 1:26-27; 1 Corinthians 6:9). Beware of other sexual sins (Galatians 5:19-21). The Bible presents nakedness as shameful and degrading (Genesis 9:21; Exodus 20:26; 32:25; 2 Chronicles 28:19; Isaiah 47:3; Ezekiel 16:35-36; Luke 8:27; Revelation 3:17; 16:15; 17:16), except for Eden’s beginnings before Adam and Eve realized they were naked, or that deal with marital relations (Proverbs 5:18-19; Song of Solomon 4).
Religious involvement (other ungodly religions, and practices from other religions that Christians try to take part): Bindis (third eye mark in Hindu culture) is associated directly with the spirituality of Hinduism and is ungodly – come out from among them and be separate, and do not touch any unclean thing (2 Corinthians 6:16–17). Horoscopes, fortune telling (including fortune cookies), and divination are prohibited in Scripture (Deuteronomy 18:10–15). Spiritual practices such as martial arts should be handled with care, as the Bible describes the mind as desperately wicked, whereas martial arts attempts to unify the body with the mind. Spiritual philosophies are dangerous if they are not set upon God, because they go against God instead. Secret societies are counterproductive to the Great Commission (Matthew 28:19). Gangs are likely sinful, since bad company ruins good morals (1 Corinthians 15:33). Pursuing wisdom in God is much better (Proverbs 1:8-19).
Costumes, cosplay, and other dressing up: Doing it for the glory of God is best (avoid scantily clad, nudism, etc. – see above on sexual immorality and 1 Timothy 2:9)(1 Corinthians 10:31).
Injustice: God hates all of it if it does not align to His Will (2 Chronicles 19:7; Job 6:29; 11:14; Proverbs 16:8; Ezekiel 18:24; Romans 9:14).
Inequality: There is no distinction to God, for all are one in Christ Jesus (Galatians 3:28). Disparity (especially racial, ethnic, or religious disparity) shall be prevented among Christians (see James 2:1-13). Instead of discrimination, we must love our neighbors as ourselves (Leviticus 19:18; Romans 13:9; Mark 12:31). What is unequal and remains unequal is human behavior, for we have many fools and few wise people (Proverbs 10:8, 14; 17:28; Ecclesiastes 9:17). When it comes to racial differences, God treats everyone equally no matter race or color (Deuteronomy 10:17; Acts 10:34; Romans 2:11; Ephesians 6:9). We should be doing the same thing, instead of committing evil thoughts (James 2:4, 8).
Freedom of acceptance: Tolerance can only go as far as obeying God; therefore, tolerating sin for example is not of God, tolerating foolishness is not of God, tolerating violence and hatred is not of God – for we are to obey God, not man (Acts 5:29). If we are to correct someone, we should take the advice as above in protesting/passivity.
Capital punishment, death penalty, etc.: The Bible supports the use of capital punishment or death penalty (Genesis 9:6; Romans 13:1-7).
Abortion: The Bible says that death should follow those who kill a baby while it’s in the womb (Exodus 21:22-25). Therefore, abortion is murder and it is not supported in the Bible. (Genesis 1:26-27; 9:6; Exodus 21:22-25; Psalm 139:13-16; Jeremiah 1:5)
Population control, depopulation: The Bible is silent about depopulation; however, the Bible does say to be fruitful and multiply, so increasing population is part of a Biblical perspective (Genesis 1:22, 28)
Feminism: This deals with the same in inequality, there is no difference of people to God, for all are one in Christ Jesus (Galatians 3:28). Feminists demand respect and equality in arrogant ways; yet they miss that all are equal in the Lord’s eyes.
(insert ethnicity or gender) matters or other movements characteristic of singling out one ethnicity over another or one gender over another such as women’s rights movements: This deals with the same in inequality, there is no difference of people to God, for all are one in Christ Jesus (Galatians 3:28).
Being born gay (same as transgender): There is no evidence that people are born gay or transgender in the Bible, and being gay (which can include transsexuality) is labeled as sin (see above on sexual immorality).
Animal rights and anti-cruelty: Proverb 12:10 says, “A righteous man cares for the needs of his animal…”
Climate change: Should it become a disaster, it is likely one part of apocalyptic judgments mentioned in Revelation 6-18. Climate change is possibly a birth pang of a New Heavens and New Earth coming eventually. Psalms 46:2-3 says to not fear climate changing, no matter what occurs.
Defending yourself: There is no set answer in Scripture regarding this. However, there are Scriptures about Christians being pacifistic; therefore, it is safe to assume there are exceptions (Proverbs 25:21–22; Matthew 5:39; Romans 12:17). Personal slights and offenses should be ignored if possible, because it solves the problem quicker than retaliation (Matthew 5:39). Using James 3:17 as guidance, we may use self-defense if we believe it is necessary, especially to save human life.
Owning weapons, gun control: Christians are called first to be peacemakers (Matthew 5:10), and if purchasing a weapon they can be peacemakers, they should also be honoring God (1 Corinthians 10:23). We know that our world is in warfare almost continually (Mark 13:7; James 4:1), and that weaponry is at use in much of the warfare. We must be aware, however, “all who draw the sword will die by the sword” (Matthew 26:52), which is to say that those who use weapons will die by weapons as well.
Terrorism and war: Repeatedly through Scripture, people are condemned for shedding of innocent blood (Deuteronomy 27:25; Proverbs 6:16–18). Terror tactics are condemned (Jeremiah 7:6; 19:4; 22:3, 17). The Bible treats ambush tactics as murder (Deuteronomy 19:11). Christians are instructed to never use bloodshed to defend Jesus Christ (Matthew 10:52). Violently overthrowing or influencing the government is prohibited as well (includes rioting and violent protesting) (Romans 13:1). Christians are instructed to overcome evil with good (Romans 12:21). The original command in Scripture is that you are not to kill, but this is associated with murder (Exodus 20:13). God often ordered war for different nations (1 Samuel 15:3; Joshua 4:13). War is always the result of sin and done to remove evil from the earth (Romans 3:10-18).
Philosophers and philosophy [This will need dynamically expanded to cover most well-known philosophy areas]: Greek philosophers were often debated by Paul, saying the Gospel of Jesus Christ was foolishness to their worldview (Acts 17:18; 1 Corinthians 1:23). Gnosticism, intellectualism, and other mystery religions were sorely rejected by church leaders (1 John 4:2–3; 1 Timothy 4:1–5, Colossians 2:6–9). To all the philosophers and people who partake in their views, they are to repent: “Therefore having overlooked the times of ignorance, God is now declaring to men that all people everywhere should repent” (Acts 17:30). We need God’s Revelation (in addition the Bible) to the see the truth, because “By faith we understand” (Hebrews 11:3). Man in his natural form cannot understand God in human knowledge alone (1 Corinthians 2:14–16). God gives wisdom to us as a gift (James 1:5). The Mind of Christ shall propel us in the direction God sets out for us (1 Corinthians 2:16; Proverbs 3:5–6).
Church planting: Waste of financial resources. It is simpler to settle within different homes and worship God and share the Bible without getting money involved all the time.
