Hi drhumm, have a listen on sermons here,( I recommend Zac Poonen's messages about Grace) hope that you'll find the difference on what Joseph Prince is teaching... I came across to his quote
“Old Testament prophets call your sin to remembrance, while New Testament preachers call your righteousness to remembrance. Old Testament preachers tell you what’s wrong with you, while New Testament preachers tell you what is right with you because of what Jesus has done, in spite of what is wrong with you.” (DTR, p.220)
it is false BASE ON MY JUDGEMENT and his message of Salvation by grace is very elementary... salvation is by grace through faith but this does not dismiss our accountability. When you are struck by the beauty of Jesus Christ you will be on fire for God that's why it is written: "continue to work out your salvation with fear and trembling" (Philippians 2:12) He also doesn't have a clear teaching on repentance, 2 Corinthians 7:10 says "For godly sorrow worketh repentance to salvation not to be repented of: but the sorrow of the world worketh death."
I also don't agree on his teaching about tithing and prosperity....I found his teachings humanistic...
I hope you will not stumble because of me...but please have time to meditate on these....
