The gift of eternal life is free, but following Jesus takes everything!
Luke 14:26
"If you want to be my disciple, you must hate everyone else by comparison--your father and mother, wife and children, brothers and sisters--yes, even your own life. Otherwise, you cannot be my disciple.
Matthew 16:24
Then Jesus said to his disciples, "Whoever wants to be my disciple must deny themselves and take up their cross and follow me."
