I’m reading Absolute Surrender by Andrew Murray. Here’s a quote I found helpful:
You may have ten hours’ hard work daily, during which your brain has to be occupied with temporal things. God orders it so. But the abiding work is the work of the heart, not of the brain. It is the work of the heart clinging to and resting in Jesus, a work in which the Holy Spirit links us to Christ Jesus. Oh, do believe that deeper down than the brain, deep down in the inner life, you can abide in Christ, so that every moment you are free, the consciousness will come: “Blessed Jesus, I am still in You.” If you will learn for a time to put aside other work and to get into this abiding contract with the heavenly Vine, you will find that fruit will come. What is the application to our life of this abiding communion? What does it mean? It means close fellowship with Christ in secret prayer. I am sure there are Christians who do long for the higher life, and who sometimes have received a great blessing. I am sure there are those who have at times found a great inflow of heavenly joy and a great outflow of heavenly gladness. Yet, after a time, it has passed away. They have not understood that close, personal communion with Christ is an absolute necessity for daily life. Take time to be alone with Christ. Nothing in heaven or earth can free you from the necessity for that, if you are to be happy and holy Christians.
