You have a lot going on. As a good man, you like to think you have your family covered. You can support your kids financially, care for your parents as needed and head up your siblings bringing order to the family if divided, but much of that can get out of our control/influence. The good thing is that the God of truth and justice is still holding all the cards ultimately and vows to balance this equation in favor of those who seek and serve Him. Believe that. I strongly suspect that this also applies to those who are not His elect. He'll even save them too if they switch sides and serve His commands instead. Now is the time for anyone on the fence to choose their god.... I received a call informing me that one of my brothers (12 years older than me) has terminal cancer.
... I've had to establish some boundaries against his passive/aggressive manipulation and mistreatment of my mother (and Dad, prior to Dad's death).
... I just have to accept that whatever the court awards my almost-ex-wife, will be whatever the court awards her. ...
It sounds like your mom is hung up on her preconceptions about what her life should have been (the original script protocol she was programmed with as a child) and therefore experiencing some distress at the contrast of how things actually turned out. However, it's probably a safe bet that things won't go as we anticipated and faith is the only solution for this kinda stress. She is in my prayers.
Just as we are born so we die, and that doesn't change. Therefore, isn't it just common instinct to live life with a righteous destination in mind? It's our only hope and ultimate payoff if you really think about it. Make your life count that you may stand proud in that day of judgement with no shame or regret following you into eternity. That's the only thing in our lives that we truly control (our personal choices) and those choices are all that we take into eternity.
Your a good man B. Stay true and know that your prayers are compounded with ours.
