From the magnificent John Barach.

You cannot give your children too much assurance of your love, and you do not need to — in fact, you must not — teach them to question their assurance in order to get them to toe the line and live the way they should.

And so it is with the church.

Presumption is deadly and pastors should preach the covenantal warnings of Scripture. But no one has ever perished because he had too much assurance, because he trusted too much that God loved him, that Jesus died for him, that the Spirit was working to glorify him.
