If you set your love on worldly things, they will not satisfy. You may as well satisfy your body with air, as your soul with earth. "In the fullness of his sufficiency, he shall be in straits" (Job xx. 22). Plenty has its penury. If the globe of the world were yours, it would not fill your soul. And will you set your love on that which will never give you contentment? Is it not better to love God? He will give you that which shall satisfy.https://www.ccel.org/ccel/watson/cordial.ix.html
To own and stand up for a hated and despised truth will bring more comfort to our souls than all the pleasure the wicked have in their sensual delights.
Christian contentment is that sweet, inward, quiet, gracious frame of spirit, which freely submits to and delights in God's wise and fatherly disposal in every condition.The Rare Jewel of Christian Contentment
The heart must be kept courageous and strong and lively, like an instrument which is tuned to tune all the rest, or else every grief will make thee impatient. In Deuteronomy 30:9 it is said that God rejoices to do us good, and therefore in Deuteronomy 28 the Jews are reproved because they rejoiced not in the service of God. As He loveth a cheerful giver, so He loveth a cheerful server and a cheerful preacher and a cheerful hearer and a cheerful worshiper; and therefore David saith, "Let us sing unto the LORD" (Ps. 95:1), showing, as it were, the tune which delights God's ears. Sermons, 115
Cheerfulness is like music to the soul. It excites to duty. It oils the wheels of the affections. Cheerfulness makes service come off with delight, and we are never carried so swift in religion as upon the wings of delight. Melancholy takes off our chariot wheels, and then we drive on heavily. Discourses 1:377
The more a man delighteth in God, and in the ways of God, the more he cleaveth to Him, and resolveth to go on in this course, and temptations to sensual delights do less prevail.
Take delight in the word of God. 'How sweet are they words unto my taste.' Psa cxix 103. Chrysostom compares God's word to a garden. If we walk in this garden, and such sweetness from the flowers of the promises, we shall never care to pluck the 'forbidden fruit.' Ten Commandments, 161
