We can also conclude, through reason, that Jesus lived, that he made certain seemingly outlandish claims, that he performed miracles and even that he rose from the dead.
Concluding that one must commit one's self to Jesus fully is a bit different, although the former can play a role in the latter. Hey, I started this thinking we diagreed on something, but I guess we agree after all! It must be getting late.
The Bible is just text to those who read with the eyes, but to those who can and do read in the Spirit, it is alive. To one who cannot see, Jesus was a good man, but to those who can see, He is the Word of God made flesh.
We can use reason to encourage someone else to look or to listen, but the power to see and to hear is a gift of God.
And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; [Even] the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. John 14:16-17
And the disciples came, and said unto him, Why speakest thou unto them in parables? He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given.
For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath.
Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand.
And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive:
For this people's heart is waxed gross, and [their] ears are dull of hearing, and their eyes they have closed; lest at any time they should see with [their] eyes, and hear with [their] ears, and should understand with [their] heart, and should be converted, and I should heal them.
But blessed [are] your eyes, for they see: and your ears, for they hear. - Matthew 13:10-16
