Too often religious people will not entertain new thoughts for fear they may accept it as true. The salvation of all is one of those thoughts. But if we trust God then we should not fear entertaining new thoughts - and we might learn the truth of the Scripture and reject the dogma of men.
“Do not let your heart be troubled; believe in God, believe also in me. In my Father’s house are many dwelling places; if it were not so, I would have told you; for I go to prepare a place for you. If I go and prepare a place for you, I will come again and receive you to myself, that where I am, there you may be also.” (John 14:1-3)
"For there is one God, and there is one mediator between God and humanity, the man Christ Jesus, who gave Himself as a ransom for all..." (1 Timothy 2:5-6)
