I am so going to get slammed for this.
I think you should question everything O'Sensei said. The only person who can lead you to a life worth living is Jesus Christ.
Human beings have always had a certain emptiness inside; a want to follow someone or something. That's why you see people get caught up in cults, hobbies, arts, etc. That emptiness was created by God. He created it so we would want to have a relationship with Him. Unfortunately, we (by ourselves) can't have that relationship, because He is a perfect God and we are definitely not perfect. He still wanted that relationship, but something had to be sacrificed, because in the Bible it says that "without the shedding of blood, there is no forgiveness of sins."
Now I'm sure you've heard the whole "Jesus" thing over and over, about Him dying on the cross, being buried, and rising again, blah blah blah. But if a guy goes through an unfair trial, gets beaten with a whip that has nine long strips of leather with glass and bone embedded in it 39 times, has to carry a 170lb hunk of wood up a hill, then get nailed to it on one of the most sensitive nerves of the body, hang there for 6 hours and finally die of suffocation, blood loss, and shock, I think that's something worthy of attention. That tells me that He put a lot of thought into what He was doing, and the Bible says that He did it for all of humankind. (Romans 5:8)
O'Sensei never did anything like that for me, and neither did the gods he worshipped.
The Bible says that He didn't stay dead, but after three days he was (brace yourselves for the ever-common church-y term) resurrected and still lives today. He promises all of those who have believed in Him and accepted Him and Him alone as their Savior eternal life. He doesn't promise a perfect and easy life, but He does send the Holy Spirit to help us. (John 14:16-17) Not ki, the Holy Spirit.
Since there has been a sacrifice, we are now free to have a relationship with God. It's easy to get it, too. All He asks is that you admit you have (another church-y term) sinned and need a Savior, believe that Jesus died for you and is the only one who can save you, and ask Him to be your Savior.
But what I am saying is that for some reason we have to look to other human's -who are human like us- for things that are really beyond what humans can do, or be, especially with spirituality.
BTW, the Bible says that Jesus 100% God and 100% Man. (John 1:14) He became flesh not only so He could die for us, but to suffer the same things we suffer through, such as hunger, pain, loneliness, betrayal, etc. In that way, we can relate to Him. He also did things waaay beyond what humans can do. The Bible holds many accounts of miracles done by Jesus.
