Too often religious people will not entertain new thoughts for fear they may be true. The salvation of all is one of those thoughts that religious people fear. But if we trust God then we should not fear entertaining new thoughts - and we should be seeking to 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 this is ideal and welcome in the sight of our Saviour, God, Who wills that all mankind be saved and come into a realization of the truth. 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 2:3-6)
"Faithful is the saying and worthy of all welcome (for for this are we toiling and being reproached), that we rely on the living God, Who is the Saviour of all mankind, especially of believers. These things be charging and teaching." (1 Timothy 4:9-11)
Humanity just cannot stop seeking and following the religion of the gods of their own making - stop it!
The true God has spoken...
"For the saving grace of God made its advent to all humanity, training us that, disowning irreverence and worldly desires, we should be living sanely and justly and devoutly in the current eon, anticipating that happy expectation, even the advent of the glory of the great God and our Saviour Jesus Christ, Who gives Himself for us, that He should be redeeming us from all lawlessness and be cleansing for Himself a people to be about Him, zealous for ideal acts. Speak of these things..." (Titus 2:11-15)
