In 1614, Pocahontas married English colonist John Rolfe in Jamestown. Having converted to Christianity, Pocahontas changed her name to Rebecca.
When Jacob wrestled with the angel and prevailed, he got a new name -- Israel. The name designated a change in his life's calling. Pocahontas experienced a change in her calling in life, and in so doing took on the new name Rebecca. We too must be willing to accept our new calling in life, and be willing to change our name and direction accordingly.
