Families are increasingly copying hymn lyrics from sources on the web, and as a result, pasting in every verse of a hymn. As a result, everyone can end up singing up to 8 verses of a hymn, to the point where it becomes a marathon rather than a pleasure.
In my mind, it is perfectly acceptable (and common practice) to cherry pick the verses of hymns. Generally, if you look at the words, if you don't recognise a verse, don't include it; chances are, it was the verse you never sang at school because it's the one with the odd rhythm in the middle line, or similar.
If in doubt, ask your minister (or us). After all, two verses less won't dilute the message of a good hymn, and gives you more time in the service too.
