Mary, remind thim of this when they ask you "What makes you think the Christian bible is right and others aren't? "
This is what you tell them
the only true God—had a Son named Jesus Christ to whom all the power of the Father was delivered (Matt 28:18), and whom died and resurrected so that His faithful children whom believed upon Him could be forgiven and thus attain eternal life.
The God of Christianity is not the same God as the god of Islam or Judaism; as the Christian's God—the only true God—had a Son named Jesus Christ to whom all the power of the Father was delivered (Matt 28:18), and whom died and resurrected so that His faithful children whom believed upon Him could be forgiven and thus attain eternal life.
Neither the Jews nor the Muslims acknowledge this great and necessary truth and thus are not to attain eternal life with God, no matter how "pious" they pretend or seem to be.
Being "nice" doesn't get you into Heaven; believing upon Jesus Christ is now, since he was once offered, the only door to Heaven. "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me . KJV " (John 14:6). Period. And to tell a Jew or a Muslim that they are not going to Heaven is not "Hate Speech," it is the greatest of love; for, who knows if they will fear and investigate and perchance come to the faith in Jesus Christ that saves?
But on the other hand, allowing them to believe that there "are many paths" to God—and allowing them to believe that belief upon Jesus Christ is irrelevant to salvation—is to enable their final utter destruction before God, the Lamb, and all the holy angels of Heaven. And it makes one guilty in part for that destroyed soul.
That is a hard truth that the greatest majority of today's lukewarm, saltless, Christ-betraying preachers dare not utter for Political Correctness' sake, get-along-with-everybody-itus , and to present a false illusion of piety, charity, and godliness. "Having a form of godliness, but denying the power thereof: from such turn away. " (2 Tim 3:5).
