1. I responded to the article, and why I disagreed, in #1442.
2. The "Got Questions" article :
"We don’t lose our sin nature once we receive Christ. The Bible says that sin remains in us and that a struggle with that old nature will continue as long as we are in this world. Paul bemoaned his own personal struggle in Romans 7:15–25. But we have help in the battle—divine help. The Spirit of God takes up residence in each believer and supplies the power we need to overcome the pull of the sin nature within us. “No one born of God makes a practice of sinning, for God’s seed abides in him, and he cannot keep on sinning because he has been born of God” (1 John 3:9)."
a. The body of sin is the sin nature, and it is "brought to nothing" as we behold Christ, just as the serpents lost their power as the Israelites looked to the Bronze Serpent.
b. Romans 7 was Paul before Christ:
i. "when we WERE in the flesh" : past tense
ii. "in the flesh" : Christians are "not in the flesh but in the spirit" (8:9), so it doesn't describe Paul's Christian life
iii. In Ro 7, Paul couldn't do the good of the Law, because his flesh didn't possess any good wherewith he might do the good, but, as a Christian, because there is good "in Christ", and Paul is "in Christ", he keeps the Law (8:4)
iv. sin killed him : Paul was not killed by sin as a Christian
v. he was a captive : Paul as a Christian was not a captive but set free (8:2)
c. No one born of God makes a practice of sinning : John wrote against the Gnostics, and many of his statements there are specific to that discussion. The Gnostics thought the material world was made by an evil god, and was evil, so as long as they lived they would continue in gross sins, AND for that reason Jesus could never have been made flesh (because flesh is evil).
