Okay.
Is it not the Spirit of God that assists in the resistance as referenced by Paul's words "God is faithful"? I believe it is clear that Paul is reference those who have the Spirit of God.
Thusly, it common with man (even those who have the Spirit of God) to be tempted.
I'm back.
There are two types of sins. Sins unto death and sins not unto death. What a born again Christian is incapable of doing are sins unto death. Those desires are never in our nature anymore. Jesus took us from death to life.
The other type of sin has to do with actions we do showing immaturity in the fruit of the Spirit. It is these trespasses we have to grow out of. That is why Peter said,
2 Peter 1:5-11
5 But also for this very reason, giving all diligence,
add to your faith virtue, to virtue knowledge, 6 to knowledge self-control, to self-control perseverance, to perseverance godliness, 7 to godliness brotherly kindness, and to brotherly kindness love. 8 For if these things are yours and abound,
you will be neither barren nor unfruitful in the knowledge of our Lord Jesus Christ. 9 For he who lacks these things is shortsighted, even to blindness, and has forgotten that he was cleansed from his old sins. 10 Therefore, brethren, be even more diligent to make your call and election sure, for if you do these things you will never stumble; 11 for so an entrance will be supplied to you abundantly into the everlasting kingdom of our Lord and Savior Jesus Christ.
If we are barren that is like John 15:1-6
“I am the true vine, and My Father is the vinedresser. 2 Every branch in Me that does not bear fruit He takes away; and every
branch that bears fruit He prunes, that it may bear more fruit. 3 You are already clean because of the word which I have spoken to you. 4 Abide in Me, and I in you. As the branch cannot bear fruit of itself, unless it abides in the vine, neither can you, unless you abide in Me. 5 “I am the vine, you
are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing. 6 If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw
them into the fire, and they are burned.
