Rev 12:2

2 She was with child. She cried out, laboring and in pain, giving birth.

she was with Child – the kingdom of heaven began with the baptism of Christ, but Christ was not yet born as the “Male Child” as we shall discover in verse 5.

being in labor and in pain – Jesus described His crucifixion as the pain of a woman in labor, in John 16:21, and this is the meaning expression of “in labor and in pain” in this passage.

The prophecy of Revelation follows the Book of Daniel. In Dan 9:26, we were told that the Latins, “the people of the ruler to come” (Dan 9:26), would cut off the Messiah, “in the middle of the week” (Dan 9:27), and “put an end to sacrifice and grain offering.” The offering for sin under the Old Covenant came to an end with Christ’s death. Christ died so that many might have eternal life. Therefore, the kingdom of heaven, was like a Woman in labor, waiting to bring life – to many.
