Young Missionaries

My Venting On The call of young missionaries. Would it not be better to have young people marry, raise kids, study the word in depth, then go out into the mission field once you are older, wiser and more experience, and with nothing to loose. Then taking a kid 19 year old, who has all of 3 years max of good Christian Education, zero life experiences of faith, try to win the world. Or are we in all agreement that proper education in the Word is of no value for "Saving Souls."
