Romans 8:4
That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
Romans 8:13
For if you live after the flesh, you shall die: but if you through the Spirit do mortify the deeds of the body, you shall live.
Galatians 5:16
if you are led by the Spirit, you are not under the law
Those that walk after the flesh, including those that got saved but backslid and/or never learned to be led by the Spirit (Jesus being their first love) are living under the law of sin and death
Romans 8:1
There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
In today's apostate church... they teach or at least imply that it matters not whether the Lord is your first love so the door is wide open to live after the flesh and they say you'll go to heaven anyway.
Just part of the end times deception going around...sadly, some will have to learn the hard way cause they still love the things of this world more then the Lord so they are enemies of the Lord (James 4:4) and don't even know it
