Do you know that good exegesis is reading the Word of God in context?
Read Romans 7 and Romans 8 together. That is the context. Romans 7 is about those trying to keep the law in their own power without the Spirit of God and stumbling over and over. Why? Because they still had SIN in their nature. (vs. 13) IOW, Romans 7 is BEFORE accepting Christ and receiving His Spirit making them born again. Now in Romans 8, Paul shows that he is now free from the stumbling around of Romans 7, so 7 no longer applies to him. Why? Because he has been freed from the sin that dominated his nature prior to receiving Christ. Romans 8:2 "For the law of the Spirit of life in Christ Jesus has made me free from the law of sin and death." Note: who was set free from the plight of Romans 7? Paul says, ME.
Romans 7
20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me.
21 I find then a law, that, when I would do good, evil is present with me.
22 For I delight in the law of God after the inward man:
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.
24 O wretched man that I am! who shall deliver me from the body of this death?
25 I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin.
If we are to believe this passage . . . do we believe this passage? If we are to believe what is written here, then let's believe what is written.
"am slaving" here is "present active", which is to say, in the writer's timeline, "I'm doing this now". If we're going to believe what it says, that's what it says. Isn't it? Am I wrong about this? Does it says, "I served", past tense?
That's how Paul wrote elsewhere, such as Ephesians 2,
2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
Here there is no ambiguity, and I believe that Romans 7 is equally unambiguous.
Much love!
