This a call for Christians to give their lives for the cause of Jesus Christ,

I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service.   And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
Romans 12:1-2

The Christian is called to be dead to sin, but alive to righteousness and holiness; acceptable to God. The only way for us to be acceptable to God is through the death, burial, and resurrection of Jesus. There is no other way.

This is not a call to martyrdom it is a call to living for Christ as a devoted, committed follower of the Christ who died for our sins. We cannot conform to the world, but to be transformed by the renewing of the mind, and that means, for myself at least, every day; maybe more than once a day, through the means of prayer, the reading and study of the word of God, by living as a true witness of the Lord Jesus. By the renewing of our minds and being a faithful witness of Jesus we prove what is that good and acceptable will of God. We will always accept the perfect will of God

Be a living sacrifice for Jesus Christ
