John 15:13
Greater love has no one than this, than to lay down one's life for his friends.
 
Romans 5:8
But God demonstrated His own love toward us, in that while we were still sinners, Christ died for us.
 
People often ask me why I'm a Christian.  Why do you talking about Christ on your blog?  Why don't you just stick with merely table tennis?  
The answer is...  Because of what God has done in my life.  Jesus came down from heaven, lived a perfect life, died the death of a criminal, all to pay for the sins that I deserved to pay.  As John 15 says, this is a greatest love.  And it wasn't that I was lovable.  God loved me even when I was a sinner and saved me.  This is the reason that I preach the truth of the Gospel on my blog.  The Gospel means "good news" and this good news is so good that it isn't meant to be kept to myself, but is meant to be shared.
