Lord, You have been our dwelling place for all generations.
One commonly accepted definition of insanity comes from none other than Albert Einstein: doing the same thing over and over again expecting different results. The sane child of God recognizes that God has been our rock in times past, is our hope and help in the present, and will work all things together for good for those who love Him and are the called according to His purpose. Because the Lord has been our dwelling place for all generations, Spurgeon admonishes us to draw, from the [His] eternal condescension, reasons for expecting present and future mercies. Thus, I am not in my right mind (the mind of Christ), if I expect something other than grace and mercy from the hand of my Father, because He has always been faithful; there is no variation or shadow of turning with Him.
Faithful Father, I do tend toward insanity; I forget your faithfulness and fall into despair. You have set my feet on the Rock; set my thoughts there as well. When I tend to despair, grab hold of my face and turn it towards Christ; I cannot help but hope when I catch sight of my Saviour! Oh, Lord I believe; help my unbelief. These things I ask because of Him who died for me. Amen.
