To the point that Cofty brings up:
First... there is a different word that is translated as abandon, than there is for the word translated as 'left/leave'. But if you find that sort of research to be more than you are willing or feel able to do yourself, then consider also the following:
A man (or woman) leaves his family for work (or training) all the time without being accused of abandoning their families. For instance... if you are a soldier, you must leave your family for extended periods of time... be that for training or during a time of war, or rescue, or any service to your country that is asked of you. If you are an athlete, you must also leave for training camps and such. If your family is permitted and can follow you, then great. If not, then you'll see them when your work or training is served and complete. Sailors leave their families for their work for extended periods of time. Travelling salesmen or oilfield workers (since that is common here as I live in Alberta) leave their familes for work for extended periods of time. Men who work overseas for extended time periods also leave their families for their work.
They work to provide for their families and/or to protect/provide for others as well (such as a man who serves in the military/navy/etc) To provide for their families... and to protect life.
The world is a smaller place now (figuratively speaking), making it possible for extended time away to be shortened with less travel time, but even today if war happens or a war is being prevented or if troops are called in to help others/protect others, etc... a man will leave his family for however long he is asked/told to do so in order to serve his country. Back then the world was a bigger place (figuratively speaking)... and a man could be called to serve his king and country for years and years. Leaving houses, fathers, mothers, brothers, sisters, wives, children, fields. This was nothing new or extraordinary... to men or to women or to children. This was also not abandonment. So mothers, fathers, wives, children, etc... were capable of surviving without the men who left for whatever work or service had called them.
The apostles were called to work and service. Not forced, but called... and they answered that call. They did not work for monetary wages. They worked for a kingdom and for eternal life... for them and for their children.
What wife or grandparent would discourage a son/father/husband from working for such a thing, for himself and for his children (and their children, and their children, etc)? Unless they did not believe that this was the Messiah (and this is the problem that some have)... as His own mothers and brothers did not at first. But would Christ have been doing them or anyone any good if he listened to them and went home with them when they came to take him in hand?
How many fathers etc, have a problem today when their sons leave their families to serve their country, serving and protecting their 'kingdom' or another kingdom and its people elsewhere?
***
Christ did not seek out the rich man to call him. The rich man came TO Christ and asked Christ what he must do to inherit eternal life. Christ told him, and it did not involve giving up his riches. But that was not enough for the rich man. He pressed for more. He asked, I have done all of these things since I was a child... but what do I still lack?
So Christ answered the question asked of Him with the truth... and an invitation.
"IF you WANT to be perfect... go sell your possessions and give to the poor, and you will have riches in heaven. Then come and follow me."
That was more than the rich man was willing to do, and so he went away disapointed. But he asked a question, pressing for more... and Christ simply gave him the truthful answer.
Bringing to my mind the saying... "If you don't want the answer... then don't ask the question."
(And it is not like Christ said... sell your riches and give them - or even a portion of them - to our cause... as many false prophets/teachers/leaders do today)
***
On top of all that... Mothers, fathers, etc... could follow Christ also. We have examples of some doing just that from the gospels. (wives would have also been accustomed to maintaining the homestead while their husbands left for work or service) Or mothers/fathers/spouses/etc could welcome the apostles and Christ into their homes when they visited, if they were willing, as we also have examples of this in the gospels. Like Martha and Mary and Lazarus; and also the mother of one of the disciples. Once the physical ministry of Christ ended (1-3 years, although I lean toward 3) were the disciples not casting nets again, and shown to have wives and children - is there any reason that was not or could not have been their loved ones from before they left to follow Christ and do the work given to them by Him and His Father?
Some things for some who are seeking truth to consider, ask about, and keep in mind.
Peace to you,
