1809.'If you are able to count them' means the fruitfulness of love and the multiplication of faith, or what amounts to the same, the fruitfulness of good and the multiplication of truth. This meaning - namely, that these are not able to be counted - becomes clear without explanation.

To “generate” something is to create it, and that idea underpins the meaning of a “generation” of people -- it is a group that was created together, at roughly the same time, from the same parents or group of parents. On a spiritual level, we can be “generators” by using what we know from the Lord to create ideas of how to be good, and also to create good actions based on those ideas -- what the Writings call things of faith and things of charity. In general, then, a “generation” in the Bible represents the spiritual ideas and activities created by a church -- with a “church” being anything from an individual believer to a group lasting thousands of years. “Generation” can also pick up specific meanings from context. For instance, when the Bible says the people of Israel were captive in Egypt for four generations, it means a state of temptation based on the meaning of “four.” When paired with “eternity,” meanwhile, “generations” represents ideas and actions surrounding love of serving others, with “eternity” representing things springing from love of the Lord. Finally, “generations and generations” is used in the Bible to represent forever.
