What is the origin of the phrase "carry one's cross"? Seems to have been a pre-Christ phrase, since Jesus himself used it while talking to the disciples (Please refer extract below)
Luke 14:26-28 (New International Version) "If anyone comes to me and does not hate his father and mother, his wife and children, his brothers and sisters-yes, even his own life-he cannot be my disciple. And anyone who does not carry his cross and follow me cannot be my disciple.
"Suppose one of you wants to build a tower. Will he not first sit down and estimate the cost to see if he has enough money to complete it?
