Pirkei Avot teaches us that, according to Ben Azzai, one must “run to perform even a minor mitzvah.” (Avot 4:2). Actually, it is impossible to measure the impact of our deeds. What may seem a small gesture on our part may have a tremendous effect on the life of another.
Take the mitzvah of Bikkur Holim for example. Bikkur Holim is hardly a minor mitzvah, however, it doesn’t take too much effort to stop by the home or hospital room of someone who is sick or recovering from illness or surgery and bring cheer. Yet many people find themselves avoiding their friends and loved ones when they need them the most because they have complicated emotions about illness or perhaps they are unsure how to behave around the sick.
Here is a link to an article I wrote on the subject that I hope you will find useful.
