I think it is because most of us are hungering and thirsting after happiness instead. We are seeking to satisfy the deep well in our heart with the things of this world instead of the Person who died for the world—Jesus Christ. I believe happiness is something you stumble over on your way to seeking righteousness. When you are serving, worshipping, and praising the Lord, happiness is a by-product.
If you will seek after righteousness, then you will be happy. What you need is to have the deepest need of your heart and life met. It is to drink of the Spirit. It is to feed on the Word of God. The deepest need of your heart will only be met in Jesus.
