The Importance of Perseverance in Calvinism

John Piper prays for his children not knowing if they are of the elect because he has not yet persevered to the end. It's impossible for even John Piper as committed as he is to know if he will absolutely with 100% persevered, says David Wallis. If God has determined for people to falsely believe that they're believers you should wonder if he's done the exact same thing to you how can you trust and worship of being like that said Wallis.
