1st Thessalonians 5:21

18 in every thing give thanks, for this [is] the will of God in Christ Jesus in regard to you.

19 The Spirit quench not;

20 prophesyings despise not;

21 all things prove; that which is good hold fast;

22 from all appearance of evil abstain ye;

23 and the God of the peace Himself sanctify you wholly, and may your whole spirit, and soul, and body, be preserved unblameably in the presence of our Lord Jesus Christ;

24 stedfast is He who is calling you, who also will do [it].
