If God justifieth the ungodly, then, dear friend, He can justify you. Is not that the very kind of person that you are? If you are unconverted at this moment, it is a very proper description of you; you have lived without God, you have been the reverse of godly; in one word, you have been and are ungodly. Perhaps you have not even attended a place of worship on Sunday, but have lived in disregard of God’s day, and house, and Word—this proves you to have been ungodly. Sadder still, it may be you have even tried to doubt God’s existence, and have gone the length of saying that you did so. You have lived on this fair earth, which is full of the tokens of God’s presence, and all the while you have shut your eyes to the clear evidences of His power and Godhead. You have lived as if there were no God. Indeed, you would have been very pleased if you could have demonstrated to yourself to a certainty that there was no God whatever. Possibly you have lived a great many years in this way, so that you are now pretty well settled in your ways, and yet God is not in any of them. If you were labeled ungodly it would as well describe you as if the sea were to be labeled salt water. Would it not?
Possibly you are a person of another sort; you have regularly attended to all the outward forms of religion, and yet you have had no heart in them at all, but have been really ungodly. Though meeting with the people of God, you have never met with God for yourself; you have been in the choir, and yet have not praised the Lord with your heart. You have lived without any love to God in your heart, or regard to his commands in your life. Well, you are just the kind of man to whom this gospel is sent—this gospel which says that God justifieth the ungodly. It is very wonderful, but it is happily available for you. It just suits you. Does it not? How I wish that you would accept it! If you are a sensible man, you will see the remarkable grace of God in providing for such as you are, and you will say to yourself, “Justify the ungodly! Why, then, should not I be justified, and justified at once?”
Spurgeon, All of Grace
