4: For as we have many members in one body, and all members have not the same office:
5: So we, being many, are one body in Christ, and every one members one of another.
6: Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith;
7: Or ministry, let us wait on our ministering: or he that teacheth, on teaching;
8: Or he that exhorteth, on exhortation: he that giveth, let him do it with simplicity; he that ruleth, with diligence; he that showeth mercy, with cheerfulness.

James 4:15

15: For that ye ought to say, If the Lord will, we shall live, and do this, or that.
