As testified, the 'Christianity' this man left for Islam consisted of music, drinking and shooting pool... but not it would appear a knowledge of the Word of God.
He uses the Torah and the New Testament to validate much of what he says, why? because he has no other source to do so. So lets look at what these two Testaments say about our situation.
First, that man obeyed Satan rather than God, making Satan and not Adam [Gen 1:26] the god of this age...
2 Corinthians 4:4
In whom the god of this world [Satan] hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
Just as it is written...
Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
Therefore, having inherited Adam's corruption we all sin, yes... every single one of us...
Wherefore, as by one man [Adam] sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned:
A statement to which the Old and New Testaments agree...
For there is not a just man upon earth, that does good, and sins not.
For all have sinned, and come short of the glory of God;
The prophet Jeremiah also expounding the state of our fallen condition...
The heart is deceitful above all things, and desperately wicked: who can know it?
As Paul points out, our situation is dire, for the good we want to do we can't continue in but kept doing the very things we hate!
14 - We know that the law is spiritual; but I am unspiritual, sold as a slave to sin.
15 - I do not understand what I do. *For the good that I want to do I can not continue in, but I keep doing the evil that I HATE.
Then Satan's plan to force a Holy God to destroy Humanity has worked!
For knowing that a righteous God must punish all acts of unrighteousness if he is to retain His right standing before Creation, Satan knows what is about to happen to each and every one of us, because having brought death into the world through Adam's sin... Satan knows that we shall all be judged for our sin after our death...
Just as people are destined to die once, and after that to face judgment,
Before which, having had our sins examined a place in Hell might be ascertained worthy of our outrages, into which we shall be cast while alive, having been previously resurrected to life for judgement...
And I [Paul] have the same hope in God as these [Pharisees] men themselves have, that there will be a resurrection of both the righteous and the wicked.
Indeed, everyone who dies in their sins having an accusation against them, shall be cast into a place in Hell ascertained at the judgement, where every hidden sin is brought to light [The Books were opened].
11 - Then I saw a great white throne and him who was seated on it. The earth and the heavens fled from his presence, and there was no place for them.
12 - And I saw the dead, great and small, standing before the throne, and books were opened. Another book was opened [those whose sins were paid by Christ], which is the book of life. The dead were judged according to what they had done as recorded in the books.
13 - The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them, and each person was judged according to what they had done.
14 - Then death and Hades were thrown into the lake of fire. The lake of fire is the second death.
15 - Anyone whose name was not found written in the book of life was thrown into the lake of fire.
Now what I want to know 'O' Muslim, is how does your moon god retain his right standing while showing mercy to rotten, stinking sinners like me? But my God has found a way though at great cost, when calling upon God the Word, His only begotten Son...
1 - In the beginning was the Word, and the Word was with God, and the Word was God.
2 - He was with God in the beginning.
3 - Through him all things were made; without him nothing was made that has been made.
...to take upon Himself Human flesh, that as a Man He might live a sinless life before taking upon Himself the punishment of us all... foretold by the Law and the Prophets...
5 - But he [Christ] was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was on him, and by his wounds we are healed.
6 - We all, like sheep, have gone astray, each of us has turned to our own way; and the Lord has laid on him the iniquity of us all.
Because as God stated from the beginning, nothing but the death of a man can account for the sins of men...
but you must not eat from the tree of the knowledge of good and evil, for when you eat from it you will certainly die.”
And what is sin?
1 John 3:4
Everyone who sins breaks the law; in fact, sin is lawlessness.
As Adam and Eve, Muslims likewise seek to cover their sin with "their own works of fig leaves"...
Then the eyes of both of them were opened, and they realized they were naked; so they sewed fig leaves together and made coverings for themselves.
But because sin can only be accounted by death, God gave them coverings of skin... meaning that something had to die...
The Lord God made garments of skin for Adam and his wife and clothed them.
And that skin pointed to Christ, whom the scripture foretold would redeem us before destroying the enemy.
And I will put enmity between you and the woman, and between your offspring [Antichrist] and hers [Christ] he will crush your head, and you will strike his heel.”
So come on Muslim, show me how your moon god can save a sinner like me who by God's own Word deserving of death, judgement and a certain sentencing to hell? Show me, why so quiet? For God, my God has already announced this salvation in the Law and the Prophets, thousands of years before an unannounced Mohammed ever appeared.
1 Corinthians 15:3-4
3 - For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures,
4 - that he was buried, that he was raised on the third day according to the Scriptures,
Yes, maybe you are bold now with your flowing robes, surrounded by like bearded men and veiled women having allowed your fallen heart to deceive you...
21 - “Do not handle! Do not taste! Do not touch!”?
22 - These rules, which have to do with things that are all destined to perish with use, are based on merely human commands and teachings.
23 - Such regulations indeed have an appearance of wisdom, with their self-imposed worship, their false humility and their harsh treatment of the body, but they lack any value in restraining sensual indulgence.
But will you be so sure when screaming in pain while laying in a hospital bed, whom soiling yourself with tubes coming out of your nose you cry out to a moon god who has offered you no certain salvation, based on nothing but your 'good works'?
Listen, I don't care where salvation comes from but as a sinner who understands that a righteous must account for every sin, I know need a saviour... and have found Him in the person of Jesus Christ foretold by the Law and the Prophets.
Salvation is found in no one else, for there is no other name under heaven given to mankind by which we must be saved.”
But if Islam offers a better salvation, a more sure promise of salvation... why are you keeping it to yourself O Muslim?
This isn't about who has the fastest growing religion, who shall win and control the fleeting age or if I'm part of your bearded gang with their dress code, but this is about either eternal life or an everlasting Hell, and if you can't show this sinner a more certain salvation... you have nothing that I want to hear.
Multitudes who sleep in the dust of the earth will awake [to be judged]: some to everlasting life, others to shame and everlasting contempt.
