Hear, O Israel: The Lord our God is one Lord. (Deuteronomy 6: 4) 

Has not the One God made and sustained for us the spirit of life? 
(Malachi 2: 15) 

You may know and believe Me and understand that I am He. Before Me no god was formed, nor shall there be any after Me. I, I am the Lord, and besides Me there is no Savior. (Isaiah 43: 10-11) 

I am the first and I am the last; besides Me there is no god. Who is like Me? (Isaiah 44: 6) 

 And there is no other god besides Me, a righteous God and a Savior; there is none besides Me. Turn to Me and be saved…To Me every knee shall bow. (Isaiah 45: 21-23) 

THESE ARE JUST SOME VERSES FROM THE OLD TESTAMENT.

Can you think of other similar ones?

The One True God in the Bible (The New Testament): 

 One came and said unto him, Good Master, what good thing shall I do, that I may have eternal life? And he (Jesus) said unto him, Why callest thou me good? There is none good but one, that is, God. (Matthew 19: 16-17, in King James Version) 

Now this is life eternal, that they know you, the only true God, and Jesus Christ, whom you have sent. 
(John 17: 3) 

Worship the Lord your God, and serve Him only. (Matthew 4: 10) 

Hear O Israel: The Lord our God is One Lord. (Mark 12: 29) 

For there is one God and there is one mediator between God and men, the man Christ Jesus. (1Timothy 2: 5)

The One True God in the Qur’an

Can there be another god besides Allah (God)? Nay,

Can there be another god besides Allah (God)?

Can there be another god besides Allah (God)?

Indeed, this message concerning the Oneness of God (i.e., Tawheed in Arabic) is the essential theme of the Qur’an.

Conclusions

1- These verses as well as hundreds of similar pieces of evidence in the Bible and the Qur’an confirm this one, eternal message that the true God is only ONE.

•  “Turn to me now and be saved, people all over the world! I AM THE ONLY GOD THERE IS.” (Isaiah 45: 22)

2- Not only does the Bible affirm that God is only ONE, but it also reveals that the true God, the Creator, is the only Savior.

• “Before Me no god was formed, nor shall there be any after Me. I, I am the Lord, and besides Me there is no Savior.” (Isaiah 43:10-11)

So, according to this affirmation, all other supposed gods or deities like Jesus, the Holy Spirit, Brahma, Vishnu, Shiva, Krishna, or Buddha are neither gods nor manifestations of the ONE TRUE GOD. 

It was because of such false beliefs that after the Jews worshipped other gods, “the Lord’s anger burned against them.” (Numbers 25: 3) Likewise, Moses destroyed the golden calf. 

On the other hand, the Essenes, an early Christian unitarian community, endured torture and persecution because they refused to exchange Jesus’ monotheistic teachings for the Pauline innovation of the trinity.

To sum up, all God’s prophets including Adam, Noah, Abraham, Moses, Jesus, and Muhammad were sent by the same God, the Creator, to convey the same message:

And since those prophets and messengers preached the same one message, their religion must be the same one! So, what is the religion of those prophets and messengers? 

Submission to the will of God is the essence of the message of those prophets. This word ‘SUBMISSION’ means ‘ISLAM’ in Arabic.

The Qur’an does confirm that ‘Islam’ is the true religion of all God’s prophets and messengers. This Qur’anic fact is also traceable in the Bible itself! And this is what will be discussed in the upcoming booklet, God willing! 

Ultimately, to attain salvation, we must receive and believe in the above-mentioned message willingly and wholeheartedly. Nevertheless, doing this is not enough! We must also believe in all God’s true prophets (including Prophet Muhammad) and follow their true guidance and teachings. This is the gateway to a happy, eternal life!

So, if you are a sincere seeker of truth and a lover of salvation, you might like to consider this NOW, before it is too late! BEFORE DEATH! It can be soon! Who knows? 

One more thing… A final thought! 

Those who are sincere, honest, serious, objective, and open-minded in seeking the truth, and after thinking critically about this one message, they may ask questions like:

 So, what is the truth?  What can I do?

You CAN sincerely believe in your only true God (Allah), believe in His last messenger, and utter the following: 

q This testimony is the first step on the way to eternal life and the real key to the gate of Paradise. 

If you decide to take this way; you can contact your Muslim friend, the nearest Islamic center, or me (I will be very happy to help). 
Yes, you can do it!
