Hi rvhill,
I tend to think this "Everything is permissible for me" which Paul is talking about extends to everything physical. As Paul had the Holy Spirit/Christ indwelling he could make such a statement.
Rom 8:1 There is
therefore now no condemnation to those who are in Christ Jesus, who walk not according to the flesh but according to the Spirit.
Rom 8:2 But the Law of the Spirit of life in Christ Jesus has
made me free from the law of sin and death.
Rom 8:9 But you are not in the flesh, but in the Spirit, if the Spirit of God dwells in you. But if anyone has not the Spirit of Christ, he is none of His.
Rom 8:10 And
if Christ is in you, indeed the body is dead because of sin, but the Spirit is life because of righteousness.
As with Paul if the Spirit is indwelling, you will be guided by the Spirit of Christ and not the lust of the flesh.
Gal 5:16 I say then: Walk in the Spirit, and you shall not fulfill the lust of the flesh.
Gal 5:17 For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish.
Gal 5:18 But if you are led by the Spirit, you are not under the law.
Gal 5:24 And those who are Christ's have crucified the flesh with its passions and desires.
You ask,
We can do what ever we want, and be saved in the next life, but we still will die in this life from our sins?
If the Spirit of Christ is indwelling you are not under the law, because His Spirit by grace will give power of your fleshly desires, sin will not have dominion over you. Therefore "everything is permissible" because you are a slave to God, not to the flesh.
Rom 6:14 For sin shall not have dominion over you, for you are not under Law, but under grace.
Rom 6:15 What then? Shall we sin because we are not under Law, but under grace? Let it not be!
Rom 6:22 But now, being made free from sin, and having become slaves to God, you have your fruit to holiness, and the end everlasting life.
I am not saying that a believer no longer sins, but they are given what is necessary for the growth and character development of the believer, not to comdemnation.
1Co 11:32 But when we are judged, we are chastened by the Lord, that we may not be condemned with the world.
I hope you get what I'm trying to say here, those with the Spirit indwelling will not partake in abominations of the flesh, you will have no desire for it and the Spirit will not allow it. This is my understanding as I see this in the scripture.
mercy, peace and love
