a) In order to become a member of the church a Christian must be prepared to sacrifice his/her life for God. A Christian must distance him/herself from his/her material things, because as Jesus said; 'it is harder for a rich person to enter the kingdom of God than it is for a camel to pass through the eye of a needle'.

So the irony is that a Christian must follow God and have faith in God, with no desires for a reward (as it is said in prayer; "work and ask for no reward...
