Flesh refers to more than just the body. It also includes the carnal mind, which is evil.
But if you have a new heart and spirit, the mind with which it is thinking is Christ's. Nothing evil and defiling comes forth from
it although our old patterns of thinking might confuse us. Temptation comes from outside, primarily, and any wrong 'lusts of the flesh' are
not sins if they are not acted upon.
The battle in the mind while choosing to resist, is par for the course, until the flesh has been retrained not to respond in certain situations the way it used to. And if a believer is constantly losing a battle in the mind, then there are only two possibilities: their 'heart' is not in the battle because they really want to do the sin, or, they don't understand the nature of their enemy.
In overcoming sin it is sometimes necessary to understand the sin and the basis of its appeal (the reason it is loved), before that intimate knowledge of it can be turned into the foundation of
a strategy to overcome that sin. More could be said, but pretending that a sin happens by accident, like Aaron's 'and out came this golden calf', is self-deception or hypocrisy or both. Between oneself and God, the facade must come down, and the sin must be fully understood from both one's own side, and God's angle of abhorrence. Only as we are
willing to have His attitudes, will we utterly defeat certain sins which we had accommodated previously, with anything from no pangs of conscience to deeply depressing guilt.
I realise there are triggers for all of us, which may vary from person to person, but as long as each individual refuses to respond by acting out, no 'sin' is being committed. Whether special prayer is needed to break certain patterns of thought or feelings, is for each individual to decide. There is grace from the Lord and mercy, and
He intends the captives to be released in this lifetime, in their experience. Eternity has begun, for believers.
If some people posting in this thread don't understand the difference between bondage and sin, there is a need to read our Lord's quote of Isaiah 61 as it appears in Luke 4, where Jesus has added 'opening the eyes of the blind'. Doctrine which is whacked out against a misunderstanding of scripture, is never going to lead to deliverance, healing, or salvation. We all need to be ready to see something in the word, which we had not seen before. The glitches in our thinking can be ironed out, if we are willing to let the Lord teach us.
For instance, for many years because of one sermon I heard about how a Christian has to lay down their 'soul life', I worked hard to comply with how I had understood that message; but in fact, spiritually, I was damaging myself, and it was not until I heard something on the radio from a man who'd been converted in prison through hearing the 23rd Psalm being sung, that I realised where I was going wrong. God had spoken to him through 'My soul He doth restore again'. What??? I was busy putting my soul to death! Time for a rethink!!! I had to bring my theology in line with God's word, not some famous book-writer's interpretation of it! And since then, God has been
able to restore me as I've co-operated with His ministrations. After all, the purpose of redemption is restoration; not merely a concept, but a spiritual and physical reality God desires to bring about in our experience.
My inner man has been healed substantially, I have a sound mind, and He certainly has not left me defenceless against sin, or powerless to overcome it.
