Doctrine and Covenants 11: 12-13

And now,  verily,  verily, I say unto thee - put your trust in that Spirit which leadeth to do good - yea, to do justly, to walk humbly, to judge righteously and this is my Spirit.

Verily, verily, I say unto you, I will impart unto you of my Spirit which shall enlighten your mind, which shall fill your soul with joy.

This reminds me of Micah's words in Micah 6:8

He has shewed thee, O man, what is good; and what the Lord require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?

Isn't it beautiful that the Lord ties these attributes to joy? Man is that he might have joy. And how do we find that joy?

We find it in living the principles that Jesus taught; by discovering for ourselves through our life experiences which things bring happiness. We grow into joy as we become the person described here - just and humble, slow to judge others, filled with love because love and the Spirit are synonymous. Oh, how beautiful it is to grow into such a person and share that joy.
