ye bhajanti tu mam bhaktya mayi te teshu chapyaham.

The rainwater falls equally upon the earth.  Yet, the drop that falls on the cornfields gets converted into grain; the drop that falls on the desert bush gets converted into a thorn; the drop that falls in the gutter becomes dirty water; and the drop that falls in the oyster becomes a pearl.  There is no partiality on the part of the rain, since it is equitable in bestowing its grace upon the land.  The raindrops cannot be held responsible for this variation in results, which are a consequence of the nature of the recipient.  Similarly, God states here that He is equally disposed toward all living beings, and yet, those who do not love Him are bereft of the benefits of His grace because their hearts are unsuitable vessels for receiving it.
