12:1I 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.

12:2And 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.

13:15By him therefore let us offer the sacrifice of praise to God continually, that is, the fruit of our lips giving thanks to his name.

13:16But to do good and to communicate forget not: for with such sacrifices God is well pleased.

4:23But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.

4:24God is a Spirit: and they that worship him must worship him in spirit and in truth.

6:14Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
