“How can we who died to sin still live in it?”
In Romans 6, “How can we who died to sin still live in it?” (Rom 6:2). This raises the question of why believers still struggle with sin. Are some believers somehow defective?
Paul contrasts the two, stating that our outer person is being destroyed as our inner one is being renewed. Our physical bodies will continue to decay until God gives us a new, spiritual body (Rom 8:23; 1 Cor 15:39–42). The first is the unbrokenness of self, forming a hard shell around the spirit. It is possible, when the outward man remains unbroken, that his spirit may be inert and unable to function.
If he is a intellectual person, his mind governs his work.
Or, if he is a generous charitable person, his emotions control
his actions. His work may appear successful, but it cannot bring
people to God. The second is the mixture of his spirit with his
unbroken self. His spirit may come forth clad with strong thoughts or
emotions of self. The result is that both his spirit and soul are mixed
and impure. Consequently, his work will bring men into a mixed and
impure experience. These two conditions illustrate how unbroken
self will weaken our service to God.
When Paul talks about being raised from the dead once we have believed in Jesus (Rom 6:4), he is talking about the spirit rather than the flesh. Second Corinthians 5:17 states, “Therefore if anyone is in Christ, he is a new creation; the old things have passed away; behold, new things have come.” Here, the old and new refers to our spirits.
