The idea of not walking after the flesh is a concept that speaks
not to a person’s behavior, but to a person’s belief, not to our
manners, but to our mindset. When we believe what Christ
accomplished for us where our sins are concerned, we are as just as
we will ever be in the eyes of God at that point. Sin has no more
effect on us; it cannot change our relationship with God because we
are in Christ. Those who are “IN” Jesus Christ are those who are
NOT walking after the faulty assumption that
their righteousness is related to their performance. Those who are
“IN” Jesus Christ are those who place no confidence in their flesh,
but understand that “in their flesh dwells no good thing”. Christ
had to crucify our identity with the flesh, the old man. Paul wants
us to agree with God to reckon our identity with our flesh as dead
and gone, but the sin nature has not died. Do we need to change our
minds about the seriousness of sin and God’s answer to that serious
dilemma we find ourselves in? Yes, we do. God has been
longsuffering in holding back his wrath because he hopes that we
will consider his goodness through his son, his goodness on our
behalf and flee to his grace. God wants us to change our mind about
who we are from fleshly perspective apart from Christ.
