Biblical explanation
The Bible itself preserves examples of different languages. Daniel contains an extended section beginning with Daniel 2:4 that is written in Aramaic. Ezra also contains sections in Aramaic, including Ezra 4:8-6:18 and 7:12-26. Most of the Old Testament, however, is written in Hebrew. The New Testament was written in Greek, the language in which the Gospel message was widely communicated throughout the Mediterranean world. The New Testament itself frequently quotes the Old Testament, sometimes in forms reflecting the Greek translation used among Greek-speaking Jews. The Bible does not give us a single verse saying, "The Old Testament is Hebrew and the New Testament is Greek." Rather, the languages are established by examining the biblical text itself. The important point is that translation has always been part of communicating God's revelation across linguistic boundaries. This is why careful comparison of translations can be useful.
Key takeaway
The great controversy reveals God's character as Christ ministers as our High Priest in the heavenly sanctuary. The dead await the resurrection, Christ's return will be visible and personal, and prophecy calls believers to faithful mission rather than date-setting or fear.
