The video above (John Piper? Test yourself: Football or Christ?) It made me think of the members of the modern Brazilian church, many are not sure of salvation because they do not know the doctrines of justification by faith and salvation by grace, believing in salvation through works. And many others have false hope and false certainty of salvation because they do not know the doctrines of regeneration and sanctification.
[Ezekiel 36: 25-27] Note: For a better understanding, read the context
- I will water you with pure water and you will be pure; I will cleanse them of all their impurities and idols; I will give you a new heart and I will put in you a new spirit; I will take away your heart of stone and give you a heart of flesh; I will put my Spirit in you and lead you to act on my decrees and obey my laws faithfully.
