A great strength of Christianity is that its reasoning abilities are ahead of its own time. Many objections, such as the "problem" of evil, were answered almost as soon as they were initially raised. On top of that, some of the greatest arguments in its favor were also posed very early on, the most powerful of which can be found in the very pages of Scripture.
One example, found in Matthew 22:41-46, was posed by none other than Jesus Himself. Quoting Psalm 110:1, Jesus asks how it is that David calls the Messiah, whom the entire Jewish community knew would be a descendant of David (and for good reason, see for example Psalm 132:11), his Lord?
Boom. Here we see Christ Himself establishing, in a way no one in the crowd could answer, that He is, in fact, God incarnate. There is only one possible way the Holy Spirit could inspire David to call his future descendant, who would sit upon his own throne, "Lord". That is if the aforementioned descendant of David was none other than God Himself. From a purely Jewish perspective, it is now 100% impossible to refute the Doctrine of the Incarnation, and by extension (we have the Holy Spirit in this same passage) the Doctrine of the Trinity.
This argument has been preserved in the pages of Scripture for 2,000 years, and to this day, not a man, woman or child has been able to show how David, through the Spirit, could call his own son "Lord", except by the Doctrines of the Incarnation and the Trinity.
But this goes further than just showing, from a Jewish perspective, that Jesus is the Son of God, the Messiah. Fulfilled prophecy should be more than enough to convince any objective observer that Jesus really is who He said He is. After all, it seems more than a coincidence that a descendant of David (2 Samuel 7:12-13) would be born to a virgin (Isaiah 7:14) in Bethlehem (Micah 5:2), enter Jerusalem on a donkey (Zechariah 9:9) and suffer for sins that were not His own (Isaiah 53, whole chapter) in order to bless not only the Jews, but all the earth, in accordance with God's promise to Abraham (Genesis 12:1-3). It's just not logical that one man could fulfill all of this, without a single blip or a failure, and not truly be whom Isaiah called "Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace." (Isaiah 9:6-7). It just makes no sense.
From a Jewish perspective, if Jesus is not the Messiah, there is no Messiah. From a secular perspective, if Jesus is not the Messiah, He's some kind of time travelling wizard, because the chances of fulfilling just 48 Messianic prophecies (Jesus fulfilled them all) is a whopping one chance in a trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion trillion. Compare that to your chances of winning the Euromillions jackpot: one in 139,838,160. Far better to put your trust in Christ than in anything this world has to offer...
