I think when Jesus said "But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also." Matthew 5:39 he meant put up with abuse, mistreatment, and injustice - do not resist an evil person and do not retaliate when attacked.

This one takes a bit of cultural context, I have a book at home that has a good section on this but I'm traveling now so I'll type this part when I get home. But the gist of it is that don't just 'put up' with it, but be kind to them. Fight violence and oppresion with kindness. draw attention to them. Force them to treat you (even if just to fight you) as an equal. Like it says in ‭‭Proverbs‬ ‭25:21‭-‬22, "If your enemy is hungry, give him food to eat; if he is thirsty, give him water to drink. In doing this, you will heap burning coals on his head, and the Lord will reward you."

I think when Jesus said "love your enemies [...] Be perfect" Matthew 5:44, 48 he meant love your enemies and be perfect.

yep, that's what He meant: "Love your enemies, pray for those who curse you". I think this ties in a bit with the cheek turning.

I think when Jesus said "If you want to be perfect, go, sell your possessions and give to the poor" Matthew 19:21 he meant sell your possessions and give to the poor.

This is what He said just before the bit about the camel going through the needle eye. A man came to Jesus and asked what he needed to do to be saved. Jesus told him to keep the commandments, and the man said that He'd done that all his life. Then Jesus said "‭If you want to be perfect, go and sell all your possessions and give the money to the poor, and you will have treasure in heaven. Then come, follow me.". The man then walked away sadly because he had a lot of stuff and Jesus said it would be easier for a camel to go through the eye of a needle than for a rich person to enter the Kingdom of God.

A lot of supply-side Jesus followers say Jesus supports the troops, and that the eye of the needle the camel needs to go through isn't actually the eye of a needle - but a gate.

yeah He meant that it would be easier for a camel (like the animal, camelus, this one) to ge through the eye of a needle (like the hole in the end of the sewing tool, the bit in the top right corner of the main picture of this article). Also lol for Supply Side Jesus.

I think the above quotes are good things to do, eventho I'm not an ethical enough person to do them.

Same here, but with God's help I come to Him, He pulls me closer, and I become more like Him. And when I fall (or jump) He comes and gets me and picks me up again.

I also think all the supernatural things Jesus is quoted as saying is bull****, and that it's better to be honest than to repeat a bunch of stupid fairy tales.

I'll have to disagree with you here, I firmly believe that Jesus is God come to earth as a human.
