Whether or not the Gospel has come to me “in power and in the Holy Spirit” is to be ascertained by the effects produced in me: not transient effects—but permanent; not simply in my emotions—but in my life. If the Gospel has come to me “in power,” it has made me realize that I am a lost sinner—guilty and undone; it has made me realize that I can do nothing to save myself, nothing which can win God’s favor. If the Gospel has come to me “in power,” it has shut me up to Christ! It has not only revealed my dire need of Him—but has shown me how perfectly suited He is to my dreadful case, and how ready and willing He is to cleanse me from my sins and to heal my wounds. If the Gospel has come to me “in power,” it has made me come to Christ as an empty-handed beggar, casting myself on His mercy, and closing with His gracious offer to receive me, and by no means cast me out. If I have done this, it matters not an iota whether some particular verse of Scripture has been deeply impressed on my mind or not.

Always like to see what Mr. Pink has to say. Thanks for sharing this!
Amen! See a modern author pursuing the same truth of the Gospel:
