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.  

Walking in the Spirit is freedom from the ups and downs experienced in the flesh.  The Spirit will always lead us in a positive, powerful direction.  The flesh and negative emotions can point us in the opposite direction.  We escape the trap and cycle of guilt and condemnation from following a dead-end road.
