Regret

My dad has never met my kids. In fact, prior to last Father's Day, I hadn't seen him since my wedding day over 13 yrs ago. I went to visit him last year after his wife (step-mom) died. It was a very pleasant and touching visit. We spent a wonderful couple of days together. Since then though, his health has rapidly deteriorated and I fear he won't make it till Christmas this year. He's in the process of beginning hemo-dialysis and and now needs 24 hr care.

Not sure what to think of it all. My co-workers are extremely supportive and eager to accomodate my schedule this summer so as to visit. Some church-going friends though ask about his salvation; and I don't know what to say. My whole concept of God's grace is not very traditional, I think. I'm just really trusting that he's so much more faithful and merciful then I can even imagine. But then if I chance it, will I regret not talking w/ him before he dies? Depending on the conversation, will I regret talking to him in the first place? He says he believes in Jesus as the Christ, reads scripture and meditates; but doesn't see the point in church. (Frankly, I don't blame him.)

So, should I be worried; should I not... should I be worried that I'm not worried about his soul? What to do...what to think...either way, regrets.
