Doesn't make sense when it comes to homosexuality. The sin mentioned in the bible, that is described in some detail, always have negative effects. You steal, jail. You kill, jail. You have sex with someone other than your wife, she murders you. What negative side effect does homosexuality have? Loving someone of the same sex passionately? Social rejection and persecution? Who cares, Christians get persecuted all day long. So what's your point with this? Sin is pleasing to us but it screws us over from the get go, except for homosexuality...it's a trap?
I don't understand your point here. Sin doesn't always end in bad consequences in this lifetime. Many thieves don't get caught and jailed, many liars are not discovered, very few wives murder their adulterous husbands. These things remain sinful though regardless of the consequences here on Earth. God decides our standards not us.
Jud 1:7 NKJV as Sodom and Gomorrah, and the cities around them in a similar manner to these, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.
This is extreme consequence. If we approve of sexual immorality we are actually hating people rather than loving them. So if you hate homosexuals by all means condone homosexuality. Pleasure on Earth is fleeting and can have disastrous consequences on judgment day.
Many sins are hidden and the only way a Christian is capable of knowing his sin is through God's word and His Holy Spirit which convicts us to change/repent/resist. If we are able to convince ourselves something against God's standards is acceptable it can only be because we have decided to rebel. At that point our conscience is not working in line with God's will and we can continue in sin and its pleasures.
Homosexual actions are sinful as any sexual action outside of man/woman marriage is. We must resist and not approve of it.
Rom 1:28-32 NKJV And even as they did not like to retain God in their knowledge, God gave them over to a debased mind, to do those things which are not fitting; (29) being filled with all unrighteousness, sexual immorality, wickedness, covetousness, maliciousness; full of envy, murder, strife, deceit, evil-mindedness; they are whisperers, (30) backbiters, haters of God, violent, proud, boasters, inventors of evil things, disobedient to parents, (31) undiscerning, untrustworthy, unloving, unforgiving, unmerciful; (32) who, knowing the righteous judgment of God, that those who practice such things are deserving of death, not only do the same but also approve of those who practice them.
