15See that none render evil for evil unto any man; but ever follow that which is good, both among yourselves, and to all men. 16Rejoice evermore. 17Pray without ceasing. 18In every thing give thanks: for this is the will of God in Christ Jesus concerning you.19Quench not the Spirit. 20Despise not prophesyings. 21Prove all things; hold fast that which is good.
