Travail connotes that we are at a narrow transition. The transitional place is a place of "crossing over." Travail means that we are in a "distressed" moment.

Travail is a specific type of prayer that births (Isaiah 66:7-9), as well as wars (Isaiah 42:12-14). When a person enters a time period or season of travail (birthing and/or warring), they will experience it as a heaviness, a weight, a BURDEN, a deep penetrating concern, or an uneasiness over a situation...

"AFTER this I looked, and behold, a door standing open in Heaven! And the first voice which I had heard addressing me like (the calling of) a war trumpet said, Come up here, and I will show you what must take place in the future." Revelation 4:1

We must basically wage war with the old mindsets that keep us from "coming up" into this divine advancement. It is an invitation to enter a Heavenly door and enter into the revelation that we need to "overcome"...
