Happiness isn’t the problem, it’s where we go looking for it.
Psalm 16:11
11 You reveal the path of life to me;
in your presence is abundant joy;
at your right hand are eternal pleasures.
Ecclesiastes 2:4-11
4 I increased my achievements. I built houses and planted vineyards for myself. 5 I made gardens and parks for myself and planted every kind of fruit tree in them. 6 I constructed reservoirs for myself from which to irrigate a grove of flourishing trees. 7 I acquired male and female servants and had slaves who were born in my house. I also owned livestock—large herds and flocks—more than all who were before me in Jerusalem. 8 I also amassed silver and gold for myself, and the treasure of kings and provinces. I gathered male and female singers for myself, and many concubines, the delights of men. 9 So I became great and surpassed all who were before me in Jerusalem; my wisdom also remained with me. 10 All that my eyes desired, I did not deny them. I did not refuse myself any pleasure, for I took pleasure in all my struggles. This was my reward for all my struggles. 11 When I considered all that I had accomplished and what I had labored to achieve, I found everything to be futile and a pursuit of the wind. There was nothing to be gained under the sun.
Romans 8:28-30
28 We know that all things work together for the good of those who love God, who are called according to his purpose. 29 For those he foreknew he also predestined to be conformed to the image of his Son, so that he would be the firstborn among many brothers and sisters. 30 And those he predestined, he also called; and those he called, he also justified; and those he justified, he also glorified.
