Why Jesus and not Buddha, Mohamed, Krishna etc...
My 13 year old son made a statement the other day that I was glad I could easily counter/answer. He said "Dad, you've got to admit that it is hard to believe that Jesus is the only way. What about all the other religions and all the people who believe in other god's?". Thank the Lord that within 10 minutes, he could easily under stand why it's Jesus Christ and NOT any other God or religion. YOU should also "[be] ready always to [give] an answer to every man that asketh you a reason of the hope that is in you with meekness and fear" (1 Peter 3:15).
Simon Greenleaf set out to prove in the court of law that the resurrection of Jesus Christ was a farce, and ended up getting saved! Please read the following link and you will ALWAYS be prepared to prove that Jesus Christ is the Son of God, who died, was buried and rose again on the third day. I got saved when I trusted in Him by faith, but since then my faith has been proven through facts.
The following link will help you to understand why the resurrection is the best documented historical fact in the history of mankind:
