According to Romans 10:17, Faith comes by HEARING and HEARING of the Word of God (with your ears). So, in Genesis 1:3, God changed the darkness to light by SPEAKING words, with His mouth, which He BELIEVED, in His heart and HEARING those words, with His ears. And in Matthew 8:26, Jesus changed a stormy situation to a calm situation by SPEAKING words, with His mouth, which He BELIEVED, in His heart and HEARING those words, with His ears. Ephesians 5:1 says, 'be imitators of God, copy Him and follow His example, as children imitate their father'. So, you too can change your sadness to joy, your darkness to light, your stormy situations to calm situations by BELIEVING the Word of God on Joy, in your heart and then SPEAKING or READING the Word of God on Joy, with your mouth and HEARING and HEARING and HEARING, the Word of God on Joy, with your ears, daily. And in addition to SPEAKING or READING the Word of God ALOUD, you MUST also read the Word of God silently or mentally daily, in order to get a better understanding and revelation. Both audible and silent reading of the Word of God are extremely important for your spiritual growth and well-being. Do not neglect to do either.    

You have shown me the path of life; in your presence is fullness of joy; at your right hand are pleasures forevermore - Psalm 16:11(NKJV)

For your anger is, but for a moment, your favor is for life; weeping may endure for a night, but joy comes in the morning - Psalm 30:5(NKJV)

Those who sow in tears, shall reap in joy. He(she) who continually goes forth weeping, bearing seed for sowing, shall doubtless come again with rejoicing, bringing his(her) sheaves with him - Psalm 126:5-6(NKJV)
