On a three-day canoe trip in Montana, author Glenn Frontin sees things in his two sons he never noticed back home in civilization.Every Christian dad knows the struggles, trials, and tribulations of trying to raise godly sons in a very ungodly world. What men often forget is the Apostle Paul's words that they are soldiers fighting spiritual battles every day in a great spiritual war. A River Calling is one dad's story of realizing how easy it is to be a passive father-on the battlefield, but not in the fight. Against the backdrop of the breath-taking American West, author Glenn Frontin illustrates how the training of a spiritual soldier is remarkably similar to the military training he received as a paratrooper with the 82nd Airborne Division. He explains that simply teaching our sons to behave is not the same as training them to be soldiers for Christ and preparing them for the battles that lay ahead. From a clear mountain stream in Montana to gigantic lakes in the Dakotas, from remote Indian lands to bustling cities, paddle down the Missouri in the footsteps of Lewis and Clark as Glenn relives the adventure of a lifetime and reflects on the lessons of fatherhood in A River Calling.
