By  theology  we  mean  a  rational  and  systematic  study  of  a  religion. It  is  an analysis  to  understand  a  religious  matter. This  analysis  helps  us  to  understand  more  truly  our  religion, and  also  in  the propagation  of  our  religion. As  we  know, Judaism  is  the  religion  of  Jewish  people. Judaism  theology follow  monotheism  i.e.  belief  in one  single  God. Moreover  Judaism  theology  says that  God  knows  every  thing, has  unlimited  power, has created  the  universe  and  is kind  to  everyone. The  essence  of  believes  of  Jewish  people is  the  written and  oral Torah. Torah  is  a  Hebrew  word  meaning  teaching, instruction  or  law. It  is  basically a  set  of  five books  of  Moses  also  known  as  five  laws  of  Moses. Moses  is the Father  and  chief  of  all  prophets. Torah  says  that  all  living  and  non  living  things  in  this  world  are  creation of  God. It  is  the  God, who  has wrought  things, workout  and  shall  work  for  ever. It says  that  creator  is  one  and  is  incorporeal  i.e.  having no  corporeal  qualities  or  in other  words  He  has  no  material  or  physical  form  of  substance. It  says  that creator was  the  first  and  will  be  the  last, and  is  the  only one  to  be  worshipped  and  none else. Torah  also says  that  all  words  of  prophets  are  true. It  says  that  all  our  deeds and our  thoughts  are  known  by  God. As  there  is  a  saying  in  Judaism, “He  who  had  formed  their  hearts altogether, He  knows  all  their  deeds”. According  to  Torah God  rewards  those  who  keep  His  commandments  and  punishes those  who  go beyond  the  limits  of  what  is  morally  acceptable. One  of  the  most  ardent  faiths  of Jewish  people  is  that  there  will  be  a  resurrection  or  rebirth  of  God, but  on  the time  decided  by  Him. It  is  believed  that  every  man  and  woman  on  earth  is  like God, with  a  spiritual  and  always  existing soul. Everyone  is  made  to  be  the I mage and  likeness  of  God. For  most  Jewish  people, earth  is the  place  where  they  are  supposed  to  enjoy  their  life, not  in  the  heaven. According  to  them, hard  work  and  education  are the  paths  directed  by  God  to  live  a  good  life. They  do  not  find  accumulation  of wealth  to  be  an  evil  act  as  long  as  it is  used  in  good  deeds  and  charity. One  can live  a  comfortable  and  cozy  life  following  moral  rules. They  also  promote  honest sex  and  marital  life, but  oppose  adultery, premarital  sex, homosexuality, abortion  and  these as  sins. They  say  that  pleasures  life  like  drinking  and  dancing  are  good  if  not   done  in  excess. One  should  not  be  habitat  of  such  things. Judaism  theology  says  that  after  death  a  person  is  sent  to  heaven  or  hell. Heaven  is  considered  to  be  dwelling  of  God  and  angels. And  hell  as  home  of devils  and  place  where  wicked  people  are  punished. Now,  if  we   talk  about  Christian  theology, then  there  is  a  very  clear  doctrine or  set  of  believes  related  to  the  Holy  Trinity. It  says  that  there  is  only  one  God, with  three  persons, the  Father, the  Son  and  the  Holy  Spirit. Each  person  is  fully God, but  there  are  not  three  Gods  but  only  one  God. Christians  consider  God  himself   as  a  community  of  love. The  father  loves  Son, and  the  Son  loves  the Father  and  this love  of  the  Father  to  the  Son  and  of  the  Son  to  the  Father  is  the Holy  Spirit. Three  persons  but  only  one  true  God. This  is  the  most  glorious  mystery  of  the  Holy  Trinity  in  the  whole  Bible. It  is  said  that  God  is  repeatedly the  God  of  Abraham, the  God  of  Issac  and  the  God  of  Jacob, symbolizing  the  Holy  Trinity. Abraham  is  God  the  father, Issac  is  God  the  Son  and  Jacob  is  God the  Holy  Spirit. In  Christianity  faith  is  the  basis  of  a  Christian’s  life, the  foundation  of  the Christian building. One  of  the  faiths  is  that  the  person, who  believes  in  the  Son, has  eternal  life, whoever  disobeys  Him  will  not  see  life, but  God’s  wrath  resets upon  him. Christians  take  baptism  a  way  by  which  the  original  sin is  forgiven. Baptism  is  a sacrament  instituted  and ordered  by  Jesus  Christ. By baptism  we emerge  as  a new  creature, a child  of God  and  receive the  gift  of Holy  Spirit. It  is believed  that  after  baptism  our  old  man  dies  and  is  buried   with Christ. Moreover It   is   hat  before   baptism you  are  a  child  of  the  devil  and  after  baptism  you  are child  of  God. A  man who  believes  in  Jesus, but  do  not  receive  baptism  in  his church  is  not  a  Christian. For  a  Christian  it  is  not  only  important  to  believe  in  God  but  also  to receive  what  God  gives  us. It means  to  give  thanks  to  God  for  everything. This  is the  secret  of  how  to  keep  ourselves  always  happy and  satisfied  in our  life. To  give  thanks  to  God  for  every thing  is  the  first  step  to  calm  ourselves  and face  any storm  in  our  life. REFRENCES:-
