The Bible tells us he that is of a merry heart hath a continual feast, and a merry heart doeth good like a medicine, but a broken spirit drieth the bones. We are told by the writer that sorrow worketh death. Anyone can plainly see why the Bible teaches that serving God is joy, peace, and righteousness in the Holy Ghost. This is why faith in His written promises, in His unwavering, never failing Word, which is from everlasting to everlasting, which never changes, brings eternal life.
Kweli imesemwa vyema na mwandishi kwamba tunateka maji kutokana na chemi chemi ya wokovu kwa furaha (Isaya 12:3). Tuiingie mlangoni pake kwa shukrani na nyumbani kwake kwa kusifu (Zaburi 100:4). Bibilia inatuambia aliye na moyo wa furaha ni mzuri kama dawa lakini moyo uliyo vunjika hukausha mifupa(Mithali 17:22).
