The joy of the Lord is your strength. 

Sing, O heavens! Be joyful, O earth! And break out in singing, O mountains! For the Lord has comforted His people, and will have mercy on His afflicted. § Behold, God is my salvation, I will trust and not be afraid; “for Yah, the Lord, is my strength and my song; He also has become my salvation.” § The Lord is my strength and my shield; my heart trusted in Him, and I am helped; therefore my heart greatly rejoices, and with my song I will praise Him. § My soul shall be joyful in my God; for He has clothed me with the garments of salvation, He has covered me with the robe of righteousness, as a bridegroom decks himself with ornaments, and as a bride adorns herself with her jewels.Therefore I have reason to glory in Christ Jesus in the things which pertain to God. § We … rejoice in God through our Lord Jesus Christ, through whom we have now received the reconciliation. § I will joy in the God of my salvation.
