¹⁷ Though the fig tree does not bud
    and there are no grapes on the vines,
though the olive crop fails
    and the fields produce no food,
though there are no sheep in the pen
    and no cattle in the stalls,
¹⁸ yet I will rejoice in the Lord,
    I will be joyful in God my Savior.

¹⁹ The Sovereign Lord is my strength;
    he makes my feet like the feet of a deer,
    he enables me to tread on the heights. (Habakkuk 3)

There lies the secret of a happy life. A life focused on the Sovereign Lord bring happiness. The Sovereign Lord is my strength (v.19)
