Romans 8:5-11
Those who live according to the flesh have their minds set on what the flesh desires; but those who live in accordance with the Spirit have their minds set on what the Spirit desires. The mind governed by the flesh is death, but the mind governed by the Spirit is life and peace. The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so. Those who are in the realm of the flesh cannot please God.
You, however, are not in the realm of the flesh but are in the realm of the Spirit, if indeed the Spirit of God lives in you. And if anyone does not have the Spirit of Christ, they do not belong to Christ. But if Christ is in you, then even though your body is subject to death because of sin, the Spirit gives life because of righteousness. And if the Spirit of him who raised Jesus from the dead is living in you, he who raised Christ from the dead will also give life to your mortal bodies because of his Spirit who lives in you.
The reason that I have found living according to the Spirit to be so crucial is that every time I'm not living as I should its because I'm living by the flesh. When my mind is on the things of the flesh, I start to have fleshly desires. Instead of desiring to live as God wants me to, I find myself living for myself and my own desires.
What is living according to the Spirit? I have asked myself that very question often. Let me explain it this way; There are two ways to live. The first way is to live as we are born and continue in that manner of living in the flesh. The second way to live is to die. You die to your own fleshly desires. The things of the flesh only rot, and disintegrate back to dirt. You die to live not your mortal life, but Christ's eternal life that is given to whom accept it.
Living according to the Spirit is much more than accepting Christ into your life, it is the release of all selfish and personal desires to then live as Christ leads you in His perfect plan. When you start to live according to the Spirit you start to realize how empty and worthless all fleshly things are. Life in the Spirit is profoundly giving up what is natural, to live not of the world, but God's will.
