1st Thessalonians 5:18

15 see no one evil for evil may render to any one, but always that which is good pursue ye, both to one another and to all;

16 always rejoice ye;

17 continually pray ye;

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;
