Luke 16:15| “He said to them, “You are the ones who justify yourselves in the eyes of others, but God knows your hearts. What people value highly is detestable in God’s sight.”
Your values and preferences determine your joy level. If you find your value and preference for the things of this world then you will have very little joy. But when your values and preferences are for the things of the Kingdom of God then joy will be yours forevermore.
In His presence is the fullness of joy. You can always find joy there. The kingdom of Heaven is righteousness, peace and JOY in the Holy Ghost! So as your values and preferences line up with that of the Lords and the Kingdom you will surely increase your joy level! Bliss be with you.
