Thanks. The stumbling isn't the issue. The issue is what constitutes a sinful life. There are grey areas here that I consider I step over so rather than say (to myself) I don't sin, I say I do. I believe the Lord knows me so he knows where I am in regard to my relationship with Him. There I leave it with Him, continuing to trust Him day by day.
I try to look for the best in others and try to encourage and help them where I am able. I judge no-one because that is the Lord's arena. If I have a dispute with someone (or vice versa), I go to that person privately and try to sort it out. This always works for me so I don't need to go further. I try to do the same in my job (as I am general manager over many commercial and residential properties.) I try to apply biblical principles, not lawfully but graciously.
I still have much to learn. I am 65 and spend much of my spare time researching all the things I don't know about the planet I live on. I am fascinated with its creation (all forms of animate life and matter) around me - what I can see and what is so small I can't see it, and the universe above, and space/time conundrums. I have written dozens of short fiction stories (various genre: humor, sci-fi, travels, parables) about the things I reflect on day by day. I write these for myself because I know what I like to read and I often pick up my own stories and read them again, and smile and wonder some more. Occasionally I post them, to my family and friends.
Life is very full and there are barely enough hours in a day to do all I want. But the Lord wisely chose just 24 hours in a day with about 8 hours for sleep for a healthy life. I hope my children and grandchildren have picked up something of my zest for learning and writing, and that they will be gracious towards others, and want to explore and extract and pass on the best from life.
