This is a comment made in the latest Study Watchtower under the main discussion of humility
11 Jehovah values humility more than ability and unity more than efficiency. Therefore, do your best to serve Jehovah with humility. In doing so, you will promote unity in the congregation (Read Ephesians 4:2, 3.
They are always so presumptuous to decide what Jehovah views are.
The only scriptures they used to support their claims is Ephesians 4:2,3 which states
2 with all humility and gentleness, with patience, bearing with one another in love, 3 eager to maintain the unity of the Spirit in the bond of peace.
This scripture does not support the idea that God values humility more than ability or unity more than efficiency.
It makes me wonder if they think that God values ability more than efficiency but I guess the point is that they don't think that neither of those qualities are very important to them and from the many stories we have heard over the decades, particularly from those working at Bethel, this is true.
Often ability relies on education and training and since they think that pride leads to a person studying for long periods of time, it's easy to see why they have made this statement.
They don't have a great deal of respect with the idea that being efficient is an excellent quality to consider in whatever we are doing, unless it's a hobby that is all about fun and enjoyment.
But the worst thing about their comment is that they put two qualities above another two qualities and they don't even relate to each other. That is, you can have humility and unity regardless of how efficient or capable a person is. It's a nonsense statement yet as part of their divine worship, they will study this and be in awe at the wisdom of the GB.
