Paul, you're practically a spring chicken if you're not 60 yet!
Regarding the "wringer" there are two promises that I hang on to, that are two sides of the same divine coin:
1. Romans 8:28 - In
everything God works for the good, the benefit, of those who love him.
2. Psalm 84: 11 -
No good thing does God withhold from those whose life is blameless
No matter what happens to you, you can see God in it if you care to look, and you will understand that it's good for you; and you
never need to worry that you'll ever miss out on something - anything - that's good for you. Just stay close to your Lord. He does the "blameless keeping" bit.
And since your wish "to grow in the certainty of his love" is in total sync with his own, you can rest assured that your days can be fulfilling, satisfying, and full of spiritual growth.
A little practical advice - if you're not already doing it or some other physical exercise, get in the habit of "walking daily," or some equivalent of keeping your body in decent shape. Walking in pleasant places can provide a lot of opportunity for meditation, reflection, and discussion with your Lord and Saviour, as well as doing at least the minimum of benefiting you physically and mentally. (Physical exercise, including walking, has been shown to have more benefit for the brain than placing chess or other 'mind' games.)
