Walk is often used by St. Paul to illustrate what it means to be a baptized believer in Christ. By the sacrifice of our Lord the love our God has for us is poured into our hearts. If the love of a good wife makes a man a better husband (It does, trust me!) then the all-encompassing love of Jesus for us as his children must transform us. It changes how we walk in this world, knowing who we are in Christ, and knowing the calling we have to love our neighbor as ourselves.
When St. Paul writes to walk by the Spirit, this is simply asking us to walk under the grace and mercy of Christ. This walk is more than knowing the words of the Gospel. It is living the Gospel in how you interact with your family, and coworkers. Being filled with the love of Jesus, received by faith, we are enabled to love in return.
Most critically, to walk by the Spirit is to be in the Word of God. The highest and greatest treasure that the Lord has given to us is His Word. By His spoken and written Word, Jesus speaks to us. In the pages of Scripture, God invites us to have a conversation with He who made us and gave up His life for our salvation.
Think about it. If you want to know what is on the mind and heart of the Lord, you have His very Word to tell you. When things in your life get too much to bear, when things seem to be falling apart at the seams, you have the Words of your Savior, ready to rescue you from the mess we call sin. Eager to comfort you with the Word of His love, that He has given Himself to you. That in Jesus you have hope in even the most hopeless situations.
What is more, when life is good, and God’s blessings are abundant, you have His Word as a foundation and guide, that you may walk in the Spirit of thanksgiving, rejoicing in all that God is and does for you.
It is for these reasons, and so many more that Ps. 119 urge us to “Store up God’s Word” In times of abundance, it serves to ground and guard our souls in Christ. In times of trouble, the store house of God’s Word brings comfort and calm.
God’s Word is our survival form sin and death. The Word of God is our comfort and hope.
