Boomer & Xer differences

i've been asking this question lately and getting 2 different answers depending upon the age of the person: "Is it alright to sacrifice your time and presence with your family (wife & kids) for the sake of the gospel?" Boomers are telling me "Absolutely!" If God is calling you to do it, he will take care of your family. Therefore you are not sacrificing your family but entrusting them to God and being obedient to his calling. They point to their own examples of colleagues who worked very hard, whose wives were fully supportive and their kids grew up healthy and following Christ. My generation, GenX, is telling me that is a conundrum. If you have sacrificed your family, you have therefore compromised the gospel. They point to the examples of the troubles Billy Graham had with Franklin, or the marital troubles the Hybels or other similar examples. How might one legitimately make a case for procreating, and then because of one's work with the gospel, delegate one's parental responsibilities to another parent or person? Let alone, how to make a case for marrying and then not being present because of one's work for the gospel?
