When I speak Krsna, it means God. God has got many names according to different religious system. But the real name is Kristo [pronounced "Kreesto"]. And you will be glad to understand that this Kristo, it is a Greek word, and it is a perverted pronunciation of Krsna, this Greek word. The meaning of Kristo in Sanskrit dictionary and the Greek dictionary always the same, about this word. And from this Kristo the word has got Christo or Christ. So even in Christian world the God's name is there. Jesus the Christ or Jesus the son of Kristo, or Krsna.
