No ray of sunlight is ever lost, but the green which it awakes into existence needs time to sprout, and it is not always granted to the sower to see the harvest. All work that is worth anything is done in faith.
We need a boundless ethics which will include animals also.
At that point in life where your talent meets the needs of the world, that is where God wants you to be.
Even if it is a little thing, do something for those who have need of help.
