The principle of Sowing and Reaping?

1 Tim 5:8
"If anyone does not provide for his relative, and especially for his immediate family, he has denied the faith and is worse than an unbeliever!"

I really wonder why my own Uncle can be so heartless to his dad. He dont even want to visit him at the hospital even when he is nearing the end of his life. No matter what wrong or how bad Grandpa was many years back, he is still his dad after all, isn't it? Don't they know the principle of sowing and reaping since they are christian too? Or is it Grandpa is reaping what he sowed? Sigh... i guess we cant blame Uncle for his hatred. But can we harbour hatred for so long??? Its a bondage that will leads to destruction! Anyway, Ireally pity grandpa....his only son is ignoring him totally. Left with only 2 "cashless" daughthers to pay for all his medical expenses :( Hummmm, come to think of it, Uncle is not afraid that his children will treat him the exact way he treated their grandpa? (Gerry's eyes rolling) Watever!

This incident sets me thinking how will I react if it is my dad? My dad is a trouble maker since young even until now, I can never imagine a man can be such a total failure all his life. Nothing good ever came out from him, all I can say is, I sympatised my grandma that she had such a immature, unfilial son. She died without seeing her son turn over a new leaf........... All her life savings had either been used up to pay loan shark, gambling den and 'chicken'!! Worst thing is, his pride blinded him to think that he is right and he is STILL RIGHT UNTIL NOW! I think he dont know how to spell "SHAMELESS"! Really dont want to bother about his watever bloody "business" outside. I really dont feel like going back to that house to face him. I would rather stay alone and have my peace......

Will I ever be judged by God if I dont wanna take care of him since he never took care of us ? I had to pay for my own poly school fees by taking up vacation jobs and my brother had to scarifice not going to JC bec we have no $ to provide him for University. Our generation suffered just because him, who dont know how to be a responsible father! Sigh! Are we obligated to take care of him too ???????
