Here are selected quotes from Ellen White's writings on joy in connection with the topics you listed: 1. Joy and Conversion: “If you will seek the Lord and be converted every day; if you will of your own spiritual choice be free and joyous in God; if with gladsome consent of heart to His gracious call you come wearing the yoke of Christ,—the yoke of obedience and service,—all your murmurings will be stilled, all your difficulties will be removed, all the perplexing problems that now confront you will be solved.” (MB 101.3) 2. Joy and the Creator: “If you live for God and heaven, pointing out the way of life to others, you will go onward and upward to higher and holier joys. You will be rewarded with the ‘Well done, thou good and faithful servant: ... enter thou into the joy of thy Lord.’ The joy of Christ was that of seeing souls redeemed and saved in His glorious kingdom.” (4T 54.1) 3. Joy and God's Word: “Just before us is the ‘hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.’ ... All whose faith is not firmly established upon the word of God will be deceived and overcome. But to those who earnestly seek a knowledge of the truth, thus doing what they can to prepare for the conflict, the God of truth will be a sure defense.” (4SP 377.2) 4. Joy and the Church: “Heaven is full of joy. It resounds with the praises of Him who made so wonderful a sacrifice for the redemption of the human race. Should not the church on earth be full of praise? Should not Christians publish throughout the world the joy of serving Christ? Those who in heaven join with the angelic choir in their anthem of praise must learn on earth the song of heaven, the keynote of which is thanksgiving.” (7T 244.2) 5. Joy in Trials or Difficulties: “Jesus has not left you to be amazed at the trials and difficulties you meet. He has told you all about them, and He has told you also not to be cast down and oppressed when trials come. Look to Jesus, your Redeemer, and be cheerful and rejoice. ... We have a Saviour who so loved us that He died for us, that through Him we might have hope and strength and courage, and a place with Him upon His throne.” (8T 128.1) “Count it all joy,” says the apostle James, “when ye fall into divers temptations; knowing this, that the trying of your faith worketh patience. ... Trials will come, but they are an evidence that we are children of God. Paul passed through great trials, but he did not despair as though his Father in heaven were dead. He rejoiced in tribulation; for he desired, through participations in the sufferings of Christ, to be conformed to his image.” (GW92 441.2) 6. Joy and God's Coming Kingdom: “Now the church is militant. ... But the day is coming in which the battle will have been fought, the victory won. ... All will be a happy, united family, clothed with the garments of praise and thanksgiving—the robe of Christ's righteousness. ... Over the scene the morning stars will sing together, and the sons of God will shout for joy, while God and Christ will unite in proclaiming: ‘There shall be no more sin, neither shall there be any more death.’” (8T 42.1) “In this hope of a sure inheritance in the earth made new, the early Christians rejoiced, even in times of severe trial and affliction. ... ‘Ye rejoice with joy unspeakable and full of glory: receiving the end of your faith, even the salvation of your souls.’” (AA 517.3) If you need more detail or additional quotes for any specific category, let me know!
