“All these events are the beginning of labor pains.”
Matthew 24:8 | cross ref: Mark 13:8.

Jesus describing these events as labor pains is also important to note as it serves as a metaphor, indicating that these escalating global disturbances are initial symptoms of much greater troubles to come, which will culminate in the final events of the end times. Jesus describes these apocalyptic events in the next verses and the Book of Revelation describes them in much greater detail.
