Darkness comes by the sovereignty of God. Are we prepared to let God do as He likes with us–prepared to be separated from conscious blessings? Until Jesus Christ is Lord, we all have ends of our own to serve; our faith is real, but it is not permanent yet.
From John 16:32-33: “The hour is coming, indeed it has come, when you will be scattered, each one to his home, and you will leave me alone. Yet I am not alone because the Father is with me. I have said this to you, so that in me you may have peace. In the world you face persecution. But take courage; I have conquered the world!”
