Be careful there-- That's falling into the trap of the "God of the self", as well as a few other things that the bible has some really harsh words about.
See Romans 8, 5 through 11.
5 Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. 6 The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace. 7 The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so. 8 Those who are in the realm of the flesh cannot please God.
9 You, however, are not in the realm of the flesh but are in the realm of the Spirit, if indeed the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, they do not belong to Christ. 10 But if Christ is in you, then even though your body is subject to death because of sin, the Spirit gives life[d] because of righteousness. 11 And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies because of[e] his Spirit who lives in you.
Basically, the stance taken of "adapting to suit the self" goes against this verse quite strongly, and the verse outright says that trying this kind of thing is NOT going to please god. In fact, the person taking this route is UNABLE to please god.
Again, this is a common fallacy I see with people arguing about the dogma of Christianity. They simply dont understand it on its own axioms, and instead make strawmen that they beat about.
The basic foundational principle in the christian dogma, is that the sin-nature of mankind makes humans unhappy when they try to abstain from sin on their own. That is why you need the intercession of the christ, and his gift of the holy spirit, which gives you a substitute nature, permitting you to feel true pleasure while also no longer being driven to commit sins. The purpose of this transformation is to make you into a spiritual being instead of a being driven by the flesh, and thus worthy of being immortal.
If you choose not to go that route, you are demonstrating being a sociopath (since the principles given by god, EG-- living a sin-free existence-- are necessary for a society of immortals to live together harmoniously for eternity, and going against this would mean that you consider yourself more important than the value of other people in such a future immortal society-- eg, sociopathy) and not worthy of being made immortal. The consequence, therefore, is for god to find you lacking, and make you dead, so you cant harm other people with your selfishness.
