¹⁰⁵ Your word is a lamp for my feet,
    a light on my path.
¹⁰⁶ I have taken an oath and confirmed it,
    that I will follow your righteous laws.
¹⁰⁷ I have suffered much;
    preserve my life, Lord, according to your word.
¹⁰⁸ Accept, Lord, the willing praise of my mouth,
    and teach me your laws.
¹⁰⁹ Though I constantly take my life in my hands,
    I will not forget your law.
¹¹⁰ The wicked have set a snare for me,
    but I have not strayed from your precepts.
¹¹¹ Your statutes are my heritage forever;
    they are the joy of my heart.
¹¹² My heart is set on keeping your decrees
    to the very end. Psalm 119:105-112

Why do you suppose that following God can cause suffering?
