How do you know that you are included in a we? How do you know that you are secure as a vessel of mercy and saved from God's wrath to come?
How do we know?
Eph 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed,
ye were sealed with that holy Spirit of promise,
Eph 4:30 And grieve not the holy Spirit of God, whereby
ye are sealed unto the day of redemption.
Rom 5:9 Much more then, being now justified by his blood, we shall be saved from wrath through him.
If you are being changed into the image of Jesus (Romans 8:29), then you will love righteousness and hate iniquity (Hebrews 1:9). Right?
Sounds good but Paul says otherwise...
Rom 7:14 For we know that the law is spiritual: but I am carnal, sold under sin.
Rom 7:15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I.
Rom 7:16 If then I do that which I would not, I consent unto the law that it is good.
Rom 7:17 Now then it is no more I that do it, but sin that dwelleth in me.
Rom 7:18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
Rom 7:19 For the good that I would I do not: but the evil which I would not, that I do.
Rom 7:20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
Rom 7:21 I find then a law, that, when I would do good, evil is present with me.
Rom 7:22 For I delight in the law of God after the inward man:
Rom 7:23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members.
Rom 7:24 O wretched man that I am! who shall deliver me from the body of this death?
WE must still contend with the Devil, the present evil age and our own carnal nature. It is a battle and a struggle, not a slam dunk.
God declared that he had written the law in people's hearts (even Gentile hearts) and that this provided a basis for conscience (Romans 2:15). Are you wanting to set that aside?
That is the New Covenant. He is writing that in those He has called to conversion. Yet, if Paul, after over twenty years of conversion, still struggled, we will also.
