I'm currently reading "The Holiness of God" by R.C. Sproul. (among other things)  I highly recommend it. 

 I read that!  I have read a lot of his stuff.  Did you see all these you can get for free?  https://www.amazon.com/dp/B09Q61X1VS?binding=kindle_edition&qid=1717297469&sr=8-27&ref=dbs_dp_rwt_sb_pc_tkin 

 Nice!
