Our Scripture reading today is Galatians 5:24-26.
Verse 25, "If we live in the Spirit, let us also walk in the Spirit."
The Christian life can be condensed down to either walking in the flesh or walking in the Spirit.  Which one will we choose?  This choice does not determine whether or not we are a Christian, but this choice is made after we become a Christian.  God's Spirit is living inside of us and is desirous of leading us to honour God in all that we say and do.  On the hand, we still have the flesh that wants to be in control as well.  
The Word of God will be the difference maker in how we choose to walk.  A daily dose of God's Word will keep us walking in the Spirit and dying to the flesh.  God's Word will strengthen us as well as reveal to us what areas of our life need to change.  It is our food that gives us the needed spiritual energy to walk the narrow way.  One could say that walking in the Word and walking in the Spirit are synonymous with one another.  If I were to stop doing one, I will stop doing the other.  
Today is a new day to walk in His Word and His Spirit!
