I can't tell you what goodness is, I can only tell you what it is like. It is like the sun that radiates everything, that warms everything, that makes everything fertile and brings forth everything.

Mk 4:14 The sower soweth the word. And these are they by the way side, where the word is sown; but when they have heard, Satan cometh immediately, and taketh away the word that was sown in their hearts. And these are they likewise which are sown on stony ground; who, when they have heard the word, immediately receive it with gladness; And have no root in themselves, and so endure but for a time: afterward, when affliction or persecution ariseth for the word's sake, immediately they are offended. And these are they which are sown among thorns; such as hear the word, And the cares of this world, and the deceitfulness of riches, and the lusts of other things entering in, choke the word, and it becometh unfruitful. And these are they which are sown on good ground; such as hear the word, and receive it, and bring forth fruit, some thirtyfold, some sixty, and some an hundred.
