So yes, God loves me, this I know for the Holy Bible tells it so. Little ones to Him belong, they are weak but He is Strong. So yes, God loves me, so why am I in cuts and scars for wanting to leave those lifestyles I agree are not good for myself? Not 'good' for myself even according to HIS Own Word(s)?
Is there a certain set of 'spiritual' physics rules that need to first be 'met' before any 'good' can come?
How many years? How many years must a person live this way before 'entering' in?
Really it depends on the specifics of what you are talking about, but in general sin carries with it attachment. If sin wasn't pleasurable and addictive, why would anyone choose it over goodness and virtue?
Humans are social and so the attachment we experience with sin isn't limited to ourselves. We are connected into social networks that resonate with our sins and that we resonate with.
So when you are trying to change your ways and detach from things you know are bad and wrong, there are going to be resistances that attempt to deter you from doing so.
Think of it in terms of the codependent relationship between a drug user and drug dealer. If you are the dealer and you try to leave your responsibilities of acting as a liaison between producers and users, you are going to get negative feedback both from your suppliers who rely on you to distribute and collect money for them; as well as negative feedback from your customers who rely on you to provide them with their substance they are addicted to and assure them that they aren't dealing with a dealer who will get them in trouble.
If you are a user and you're trying to quit using and go free, your body/mind is going to be hurting you with withdrawal symptoms of your addiction; plus your dealer is going to be pushing you to give up resisting and just fall back into using and giving up your money on a regular schedule.
So you see, in this example alone, it is a painful and difficult process to withdraw from such a negative situation, and you cannot predict how long or short it will take until the negative/painful symptoms (both psychological and social) subside. You just have to keep bearing your cross and enduring suffering in hopes of deliverance. The more you count your blessings and focus awareness on how things could be worse, you will appreciate God's grace and mercy, because just imagine how much worse things would be if they were as bad as they could possibly be!
