"There is sufficient evidence for believing the Christian faith"?

Which Christian faith? They really don't have sufficient evidence, though you may think that. The truth is projected by God Almighty, and will make it apparent that God knows best who will follow His Guidance, and that He bestows His bounties upon whomsoever He wills.

A Hindu may make the same claim.
Where do these claims stand in regards to the truth?

God Almighty did not leave us neglected or abandoned; He gave us the capacity to know the truth with certainty and without any doubt.
He does not desire injustice for us.

What doubts could the sincere servants of God among the people of Moses have had? Truly, they had certainty and the Torah in which there were all kinds of enlightenments and decisive explanation of all things.
The Promised Prophet like Moses, Muhammad ﷺ, came with even greater signs and evidences. Like Moses, Muhammad ﷺ was accepted by his people, and not due to fulfillment of previous scripture, but by virtue of the qualities of Prophethood, and the Message he came with.

With the true exposition of God, Muhammad ﷺ delivered empirical and doubtless confirmation of the Message of God and all of the Prophets and Messengers.
This case, for the religion of Abraham – which is making religion completely and sincerely for God Almighty alone – is definitive.
God intends to prove the truth with His words, and to uproot the disbelievers – in order to confirm the truth and nullify falsehood, even though the guilty dislike it. To God belongs the conclusive argument. Had He willed, He would have guided you all.
And God upholds the truth with His words, even though the sinners detest it.

Believe what? Be honest, there can not be "sufficient evidence" to believe two contradictory things.
The truth stands out clear from falsehood.

The overwhelming evidence is to the contrary of the Christian assumptions of hearsay; and delusion is belief in light of overwhelming evidence to the contrary.
In fact, historically, this belief of the Messiah crucified and resurrected does not trace to the Disciples but to Paul, who never met the Messiah and has no authority from God. Yet, historically, the belief that the Messiah was NOT crucified is traced to Peter himself. This FACT is CONFIRMED by a clear Prophet ﷺ from God Almighty, and the Book of God Almighty, in which there is no doubt.
That your church sought to replace & remove the belief of the Messiah as "heretical" shows the might of God Almighty that He caused it to prevail.

Further, the evidence for the Prophethood of Muhammad ﷺ obliterates any possibility for doubt and leads to the certain conclusion as to the reality of God and His Prophets.

This is that which your eternal reckoning hinges on.
If you had sufficient evidence, then you'd have it clearly presented and it would be something that offered complete certainty.
That is the case only in Islam, which is why you are unable to scrutinise it, and unable to offer a defense for your delusion.

As God Almighty says, in the 18th verse of the 21st chapter of the Qur'an:
"Nay, We hurl the Truth against falsehood, and it knocks out its brain, and behold, falsehood doth perish! Ah! woe be to you for the (false) things ye ascribe (to Us)."

Porphyry in the 3rd century hinted at many contradictions in the Gospels. He summed up his view by stating, “The evangelists were fiction writers, not observers or eyewitnesses to the life of Jesus. Each of the four contradicts the other in writing his account of the events of his suffering and crucifixion.”
	Macarius Magnes, Apocriticus. II. 12-15 (tr. R. Joseph Hoffmann, Porphyry's Against the Christians: The Literary Remains, Amherst, NY: Prometheus Books, 1994, p.32)
Origen, as one of the strongest earlier apologists, felt the urgency of a human “interference” to save the holy status of the Gospels. He wrote: “If the discrepancy between the Gospels is not solved, we must give up our trust in the Gospels as being true and written by a divine spirit, or as records worthy of credence, for both these characters are held to belong to these works.”
	Origen, Commentary on John, X. 2.

Are you saying that you wouldn't worship God Almighty if He did not need anyone to die for you, but He exercised forgiveness and delivered us into guidance by His Compassion and Mercy?

Are you saying you wouldn't love the Messiah if God Almighty made him blessed wheresoever he is, and honored him and raised him up as He promised in Psalm 91?

If it had been God’s will, could anyone have prevented Him from destroying the Messiah, son of Mary, together with his mother and everyone else on earth?

Can those believers who stand on clear proof from their Lord be like those whose evil deeds are made appealing to them and only follow their desires?

Our way of life is a completed prescription perfected by God Almighty -- the only acceptable Way in God's sight is complete submission to His Will.

He doesn't need anyone to die for that, and neither do we. He makes clear in the Tanakh and in the Qur'an that "Forgiveness is always available to those who repent" and "repentance atones for all sins"; how is it that you expect to invite me to that which I have no knowledge of, while I invite you to the Mighty Forgiver? Why should I reject such a loving, merciful teaching of the Most Just, and require someone born of any woman to die for me?

He loves to forgive me and loves me to repent; He is the Most Loving, and always has been and always will be.

He shows mercy, compassion, and care for His creation coherently; thus He doesn't stuff all of salvation into a single moment in human history.

In God's Religion, the salvation offered through all of the Prophets has been the same throughout history: submission to our Creator.
This is the true understanding of God Almighty as having Love and Compassion inscribed on His very nature.
