AREN'T CHRISTIANS EGOTISTICAL AND INTOLERANT TO CLAIM
THEIR RELIGION IS THE ONLY WAY TO HEAVEN?
We must read the "scriptures" of other world religions and try to prove their divinity.
The only "scriptures" that can be proven by external evidences (prophecies of nations come true, scientific facts, etc.) is the Bible.
By the same token, it is not egotistical and intolerant to say that penicillin is the only cure for certain diseases.
