Sense of pardon is the true ground of spiritual joy. Christ's usual receipt for working of comfort is this: "Be of good cheer; they sins be forgiven thee" (Matt. 9:2)Christ All and in All, 311
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 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.

eternal salvation is seeing and enjoying the eternal God. Consequently, it is an inseparable joining or knitting to himThe Decades https://www.monergism.com/decades-ebook
The joy which answers to prayer give, cannot be described; and the impetus which they afford to the spiritual life is exceedingly great.Answers to Prayer From George Müller’s Narratives
The first great and primary business to which I ought to attend every day is to have my soul happy in the Lord.The Autobiography of George Muller, Whitaker House, 1984
The enjoyment of God is the only happiness with which our souls can be satisfied. To go to heaven, fully to enjoy God, is infinitely better than the most pleasant accommodations here.Living for God’s Glory: An Introduction to Calvinism, Reformation Heritage Books, 2008
This persuasion of our future enjoyment of everlasting happiness cannot tend to licentiousness, if we understand well, that perfect holiness is a necessary part of that happiness; and that though we have a title to that happiness by free justification an adoption, yet we must go to the possession of it in the way of holiness (1Joh. 3:1-3). The Gospel Mystery of Sanctification: Growing in Holiness by Living in Union with Christ
You must be good soldiers of Jesus Christ and never cease to fight until you have obtained the victory. Neither hopes nor fears, neither joys nor sorrows, must be suffered to alienate you from him or to damp your zeal in his service.
A heavenly mind is a joyful mind; this is the nearest and truest way to live a life of comfort, and without this you must need be uncomfortable. Can a man be at a fire and not be warm? Can your heart be in heaven, and not have comfort?
Godly sorrow is not an enemy but a friend to holy joy. I have read of a holy man who, lying upon his sickbed and being asked which were his joyfulest days that ever he had, cried out, "O give me my mourning days, give me my mourning days again, for they were the joyfulest days that ever I had." The higher the springs of godly sorrow rise, the higher the tides of holy joy rise; his graces will flourish most who evangelically mourns most. Grace always thrives best in that garden (that heart) that is watered most with the tears of godly sorrow. He that grieves most for sin will rejoice most in God, and he that rejoices most in God will grieve most for sin.
There are three expressions of a great joy in Scripture: the joy of a woman after her travail, the joy of harvest, and the joy of him that divides the spoil. The exultation of all these is wrought upon a sad ground; many a pain and tear it costs the travailing woman, many a fear the husbandman, perils and wounds the soldier before they come at their joy, but at last are paid for all, the remembrance of their past sorrows feeding their present joys.
Joy is the highest testimony that can be given to our complacency in any thing or person. Love is to joy as fuel to the fire. If love lay little fuel of desires on the heart, then the flame of joy that comes thence will not be great.
Is there nothing that will preserve holy boldness, enthusiastic activity, and overflowing joyfulness? Yes, there is. The recipe is found in remembering the living Jesus.
A lively impression of his love, or of his sufferings for us, or of the glories within the veil, accompanied with a due sense of the misery from which we are redeemed; these thoughts will enable us to be not only submissive, but even joyful, in tribulations.
Spiritual things truly satisfy! The more that heaven is in us—the less earth that will content us. He who has once tasted the love of God, his thirst is much quenched towards earthly things. The joys of God's Spirit are heart-filling and heart-cheering joys; he who has these, has heaven begun in him!https://gracegems.org/Watson/art_of_divine_contentment2.htm
The reason why our souls are so empty of joy, is because our mouths are empty of prayer.
Both prayer and praise widens the heart for receiving more of Christ's fullness.Works 1 - 33
Joy is something very deep and profound, something that affects the whole and entire personality. In other words it comes to this; there is only one thing that can give true joy and that is contemplation of the Lord Jesus Christ. He satisfies my mind; He satisfies my emotions; He satisfies my every desire. He and His great salvation include the whole personality and nothing less, and in Him I am complete. Joy, in other words, is the response and the reaction of the soul to a knowledge of the Lord Jesus Christ.Life in Christ, 30
If you want to try your hand at stoicism, forget the Bible. It has little for you. Scripture does not support the idea that our motives are more pure the less we are pursuing our own joy. Nope. In fact, according to the Bible, unless we are pursuing our happiness we cannot even come to God: for whoever would draw near to God must believe that he exists and that he rewards those who seek him. (Hebrews 11:6).http://www.desiringgod.org/blog/posts/pleasure-is-the-measure-of-your-treasure
the Christian tastes God in all his or her pleasures, and this increases them, whereas for other people pleasure brings with it a sense of hollowness which reduces it. God Has Spoken (14)
