Universalism is guilt writ large. It is fear based in uncertainty and, ultimately, distrust of God.
A Christianity which fancies it needs no hell is a Christianity lacking a Bible and based in sentimentalism. Indeed, it is a Christianity which has done away with the Word and embraced a menstrual rag in its place and called it sweet love.
It in fact isn’t Christianity at all but a hollow self obsessed cult of ‘me-ism’ whose god is nothing but a postulate. It is delusional and self-deceptive and lifeless narcissism.
