Again, if we are not subject to carnal temptations and do not sin anymore as the scripture says, then how can a Christian loose their salvation,
By forsaking God and returning to the ways of darkness.
and if that is true, then what is there to "overcome"?
Overcome the memories of the "good" feelings you had while you partied with the unbeliever.
Overcome the folks who once were your friends but want you to join them in their debauchery.
Overcome the allure to go to the beach to watch girls.
Overcome the false hope of false religions.
Overcome the self absorption that caused you to refuse to give some money to the pan-handler.
Overcome the fatigue that prohibits you from answering the phone.
And a hundred other things.
1John 3:9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
I sure am glad God protects me from any temptation I can't handle. (1 Cor 10:13)
Correct me if I'm wrong, but it seems you think those reborn of God' seed Christians don't have any duties to perform to ensure their redemption.
That we can just sit around watching TV until the return of Christ...or something.
Not hardly.
As much as the devil works on the unbelievers and the wicked, he works twice as hard on the folks who have subjected themselves to God.
We are in a war: and that war will not end till Jesus returns.
We can either fight back or surrender to the devil.
It is written..."Submit yourselves therefore to God. Resist the devil, and he will flee from you." (James 4:7)
These words are true.
