Isaiah 55:12

But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,

Now the God of hope fill you with all joy and peace in believing, that ye may abound in hope, through the power of the Holy Ghost.

Sing, O ye heavens; for the LORD hath done it: shout, ye lower parts of the earth: break forth into singing, ye mountains, O forest, and every tree therein: for the LORD hath redeemed Jacob, and glorified himself in Israel.

And he brought forth his people with joy, and his chosen with gladness:

Sing, O heavens; and be joyful, O earth; and break forth into singing, O mountains: for the LORD hath comforted his people, and will have mercy upon his afflicted.

And the ransomed of the LORD shall return, and come to Zion with songs and everlasting joy upon their heads: they shall obtain joy and gladness, and sorrow and sighing shall flee away.

The pastures are clothed with flocks; the valleys also are covered over with corn; they shout for joy, they also sing.

Behold, I will bring it health and cure, and I will cure them, and will reveal unto them the abundance of peace and truth.

Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:

For the mountains shall depart, and the hills be removed; but my kindness shall not depart from thee, neither shall the covenant of my peace be removed, saith the LORD that hath mercy on thee.

Go ye forth of Babylon, flee ye from the Chaldeans, with a voice of singing declare ye, tell this, utter it even to the end of the earth; say ye, The LORD hath redeemed his servant Jacob.

And all thy children shall be taught of the LORD; and great shall be the peace of thy children.

Yea, the fir trees rejoice at thee, and the cedars of Lebanon, saying, Since thou art laid down, no feller is come up against us.

Strengthened with all might, according to his glorious power, unto all patience and longsuffering with joyfulness;

Therefore the redeemed of the LORD shall return, and come with singing unto Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; and sorrow and mourning shall flee away.

And out of them shall proceed thanksgiving and the voice of them that make merry: and I will multiply them, and they shall not be few; I will also glorify them, and they shall not be small.

Likewise, I say unto you, there is joy in the presence of the angels of God over one sinner that repenteth.

The voice of joy, and the voice of gladness, the voice of the bridegroom, and the voice of the bride, the voice of them that shall say, Praise the LORD of hosts: for the LORD is good; for his mercy endureth for ever: and of them that shall bring the sacrifice of praise into the house of the LORD. For I will cause to return the captivity of the land, as at the first, saith the LORD.

O clap your hands, all ye people; shout unto God with the voice of triumph.

And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.
