All of It
If anyone chooses to become a Christian they must give every part of their life to God. This should be considered before asking Jesus to rule and lead your life. Jesus stressed this point in several ways to a crowd that was following Him in the book of Luke.
25 A large crowd was following Jesus. He turned around and said to them, 26 “If you want to be my disciple, you must, by comparison, hate everyone else—your father and mother, wife and children, brothers and sisters—yes, even your own life. Otherwise, you cannot be my disciple. 27 And if you do not carry your own cross and follow me, you cannot be my disciple.
28 “But don’t begin until you count the cost. For who would begin construction of a building without first calculating the cost to see if there is enough money to finish it? 29 Otherwise, you might complete only the foundation before running out of money, and then everyone would laugh at you. 30 They would say, ‘There’s the person who started that building and couldn’t afford to finish it!’
31 “Or what king would go to war against another king without first sitting down with his counselors to discuss whether his army of 10,000 could defeat the 20,000 soldiers marching against him? 32 And if he can’t, he will send a delegation to discuss terms of peace while the enemy is still far away. 33 So you cannot become my disciple without giving up everything you own.
34 “Salt is good for seasoning. But if it loses its flavor, how do you make it salty again? 35 Flavorless salt is good neither for the soil nor for the manure pile. It is thrown away. Anyone with ears to hear should listen and understand!”
