Raise your consciousness and increase your joy. We are responsible for our joy. Knowing where joy comes from and how to keep it is explained in this Psalm.
Psalm 97:11
Amplified Bible (AMP)
11 Light is sown for the [uncompromisingly] righteous and strewn along their pathway, and joy for the upright in heart [the irrepressible joy which comes from consciousness of His favor and protection].
This one passage by itself encompasses a lifetime of wisdom. It shows God’s preparation for you and me. It states that, “light is sown”, this means it was plant or created for the righteous. And then it is thrown along our pathway. So even when we are in a place of darkness God shines light on us. Those with an upright heart receive joy along the path.

The type of joy we receive is “IRREPRESSIBLE” (it cannot be pushed down). There is nothing or no one that can steal your joy. This joy comes from you and I being conscious or fixing our mind on God’s favor and protection. All paths in life have darkness but, with the right mind set we can live every day in His glorious light.

Be delighted with yourself. You have to have an upright or a happy spirit for God to give you gladness.
