Of course it must be this way. This is a worthy and fulfilling change. However, I think it's a change that must be tempered a bit. We must strike a responsible balance in this change.
The temptation for me now (and I think for many parents) is to pour all our energies into our children. That sounds sacrificial, courageous, and even heroic, real parent-of-the-year material; but after thinking about this, I don't think that it's a terrific path. Yes, we are called to "build up a child in the way they should go," but I think we've got to be careful in the strategy.
Rather than giving up my life in order to live through my children, I should list what kind of a life I want for them, and be that. My kids don't need me to quit living and advise them; they need me to be a role model. Words are decent teachers; actions are much better ones.
What do I want for my daughters? A devoted marriage with a strong husband? Then I should be the ultimate husband in my home. A devoted prayer life and passion for God? Then I better have that for myself as well. Healthy living? Strong relationships? Fiscal responsibility? Constant personal improvement? Do my actions say those are important? Am I displaying those in my life?
I already see it in my girls. For better or worse, I've devoted a lot of the past 3 years to grad school. Elise, who is 4, will now disappear for about 20-30 minutes and report back that she's been working on her grad work. I've never told her education is important - my actions have communicated to her priorities. No matter how often I tell my girls that flatulence at the dinner table is a bad idea, my actions speak louder than my words (in more ways than one, unfortunately). They are watching - words mean little.
Were my friend and I right about life being over? Absolutely - our old lives are over. We carry a greater burden, a responsibility to more people now. But a new life is required. Now I've got to pursue all the things I want for my girls and act on those goals/dreams, not just talk about them. It's time to get busy living. . .
