Love

I am studying 1 Corinthians 13:4-11 and I see that the King James Version uses the word “charity”, but the New King James Version and many other translations uses the word “love”. Is “love” the accurate word? And verse 10 says, “But when that which is perfect has come, then that which is in part will be done away.” Is this referring to Jesus?

“Lately, God has been walking with me on a new journey and I’m learning a lot, and fasting is something I’d like to know more about. … Do you fast? Is it true that you can fast food but still drink liquid during the fast? Can you fast things like TV and the Internet?”
