Variety: Psalm 100v1-2

Rejoice Always  1 Thessalonians 5:16
‘Shout for joy to the Lord, all the earth. Worship the Lord with gladness; come before him with joyful songs.’ PSALMS 100:1-2
Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ (Ephesians 1:3).

The injunction to rejoice cannot be interpreted as a general exhortation to Christians to ‘be happy at all times’. Happiness is not at our command, and cannot be turned on and off like a tap. Instead, Paul is issuing an invitation to joyful worship – a celebration of what God has done and given through Christ.
