In the book of Job, God tells the Accuser, Satan, that mankind can retain his/her faith in God, so Job is chosen to be tested. Job suffers, coming across miserable accidents. God trusts him as He trusts human beings and Job doesn’t fall short of His expectation. From here we can perceive another essential thought concerning Christianity: mankind cannot guess what the Divine One intends to do. What mankind has to do is to doubtlessly comply with His order and retain their unwavering faith in Him.
In the book of Exodus, in Mount Sinai, the Lord makes Moses convey the Ten Commandments in the form of two tablets, regulating what mankind should or shouldn’t do. It is considered that Moses’ Decalogue lays importance on Christian principles.
Finally, we can regard Jesus as a revolutionist of Judaism. In fact, the Jews mistakenly think that Jehovah is the only god belonging to the Jews, not to Gentiles, that is, He always stands for the Jew. However, Jesus refines God’s image that non-gentiles can convert to Christianity under His universal mercy. Therefore, Christianity is widely spread and we view it as Jesus’ devotion that not only can Jews get salvation through believing in God but the non-Jews can.
In general, Adam, Job, and Moses originate central notions of Judaism, and they still have a great influence on Christianity; Jesus has strongly direct effects on shaping Christian thoughts. The former’s contributions represent His Absolute Justice; the latter not only justice but also His Infinite Mercy.
