'About pleasing the sinful flesh'.... i believe it is God given wisdom as to where you draw the line... and whenever i have a doubt about how i should react/behave in a given situation i feel the best person to look to for help is Jesus..to look at His life on earth and think of what He would do...and from doing this i have learned the following...hope it helps
I believe earning money dishonestly pleases the sinful flesh this would involve.... not paying taxes,haggling too much with a poor vendor on the price of potatoes,taking dowry,stealing (getting money for charities orphanages etc and using it for your personal purposes), having part of the money as black money when you sell your apartment/house,making money in the name of Christ.
More for men... watching pornography on the internet would be pleasing sinful flesh.
To be preoccupied with me,myself and I would be pleasing the flesh..Jesus said if someone were to wrongfully take your coat give Him your tunic also!!
However strangely.... these things are not stressed on!... as if you notice,.. you can do/not do all these things and nobody would know as it is not visble on the outside as to what you are doing in such issues of pleasing the flesh!!
On the other hand jewellery is visible and so is given undue stress... which is another sign of pleasing sinful flesh... when you want to appear holy before men.
One of Jesus parables was about a woman who looses one coin from her head jewellery and was happy when she found it.. so that tells me that Jewellery didn't matter to God as long as it didn't take His place in your life..the same holds true for most things..
We read about Jesus attending a marriage and turning water into wine... people argue saying it wasn't fermented... but if you read the comments of the people who drank the wine they talk about how usually the best wine is served first and not last... that would be the custom only if people were too drunk to notice the difference..so Jesus was drinking alcohol at that wedding and one of His first miracles was making alcohol !! Its because of such things that the Pharisees called Him a winbiber and a glutton..but was He??
He associated with the dregs of society prostitutes, tax collectors,lepers,beggars,cripples and simple working class people like fishermen and He was a friend and healer to them... none of them as far as we know from the bible ever avoided Him/criticizedHim/argued with Him unnecessarily!!...the people who avoided Him and always Had some criticism or argument for Him were the respectable,honourable, religious establishment of that day..even non hippocritical people like Nicodemus who belonged to the religious establishment of that day came to Him at night to learn from Him to avoid being seen...
I am not going to make inferences from all this.. but i think it is sufficient to say that the one thing on this earth that speaks the most about God's intention for man's lifestyle,attitude,behaviour is the life Jesus lived here on earth.
