24 Now those who belong to Christ Jesus have crucified the flesh [sin nature] with its passions and desires.
The key for the Disciple is to daily make the decision to live a gospel-centered, cross-centered and Jesus-centered life and ensure that in our hearts we are seeking God in repentance and faith. This is the opposite of letting our sin nature control our life.
25 If we live by the Spirit, let us also walk by the Spirit. 26 Let us not become boastful, challenging one another, envying one another.
This is called living by the Spirit and should result in walking by the Spirit. “Walk” means staying in step with a line of soldiers. Writing this brings painful memories of trying to learn to march in step at Lackland Air Force basic training in 1960. I simply have no rhythm and could not stay in step. After a week or so of instruction, my tough drill sergeant realized I was trying but could not march. At that point, God intervened and he did not kick me out of Basic Training but ensured I had barracks duties every time we had parade time with all the other platoons.
The Spirit led Disciple will walk in step with the Spirit and in unity with one another as opposed to the world’s way of boasting, challenging and envying.
22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control; The fruit of the Spirit explained
The person filled by the Spirit will receive great content from the Holy Spirit including the nine fruit of the Spirit above.
