When He converted you, He forgave all your sins, every one of them. He did not leave half of them unforgiven, but blotted them all out as a thick cloud to be remembered against you no more forever. He also adopted you into His family and sent His Holy Spirit into your heart to tell you that blessed bit of heavenly news; and that information made you feel happier than to have been told that you had fallen heir to a million dollars, or been elected governor of a state, for this made you an heir of God and a joint heir of all things with our Lord and Saviour Jesus Christ. Glory to God! It is a great thing to be converted.
