Sin needs to be punished and Jesus was punished in our place but if we don't receive what he did for us then we'd need to undergo that punishment, easy peasy to understand, I understood this the first year I was born again 32 years ago.

 It's more important to understand that we are the Church and not so much going to church

 The God of the Bible is not a god of mythology. atheists call Him mythology because atheists are without God in this world Ephesians 2:12, they are blinded by the god of this world Satan 2 Corinthians 4:4, atheist and those who worship false gods and false religions are spiritually dead in their trespasses Ephesians 2:1-3, the message of the Cross is foolishness to those who are perishing, the fool says in his heart that there is no God nor there is no sign of God yet we are surrounded by proof of a creator, you would not exist if God did not exist since He did create Man in the Beginning, I hope that helps.

 There's a difference between losing your salvation and walking away from your savior and in walking away from your savior you're walking away from your salvation and if you walk away from your salvation most probably you will lose your salvation. The whole process is Progressive it doesn't happen overnight. I believe what happened to Lucifer and Adam is a great reminder and warning. Just my opinion so don't crucify me, and there's other verses we could look at through the New Testament even though many scholars have coined the epistle to the Hebrews the Epistle of warnings. The whole new testament is full of warnings and commands and imperatives.

We're saved by grace through faith, we are healed by grace through faith so why does he teach that we need to give money or things in order to prosper? That means we prosper by works, confused or what? 

 Romans 12:2 says in the original stop conforming to this world so if you keep conforming to this world I'm not sure what's going to happen but I would not want to find out, in Ephesians 4:22 it says to put off the old man which includes mind renewal in verse 23 in order to put on the new man in verse 24 which brings us back to Romans 12:2 regarding mind renewal so what happens if you don't put off this old man, and another example out of many examples in James 1:21 it says the implanted word which is able to save, deliver, transform your psyche and not your spirit since we are spirit soul and body all of this in context with superfluity of naughtiness and wickedness in verse 21 so what happens if you don't do those things over a period of time? Doesn't look too good to me and I'm not about to find out but it's in the word of God, the New Testament is filled with warnings towards Saints and not only sinners.

 There's so much false teaching out there to pick and choose from it's like a smorgasbord or buffet of False doctrination, and so many people whether they are saved or not have no discernment including those who are saved, they've not done what it takes to inoculate themselves against deception so when deception shows up especially on social media platforms in their search for truth they see it as truth and not deception and they begin to build their system of beliefs around that doctrine to the point where they become fully convinced of it as truth yet the whole time it's not only erroneous but heretical, that's the way I see things, hope that helps
