The heavens proclaim the glory of God. The skies display his craftsmanship. Day after day they continue to speak; night after night they make him known.
But when the Father sends the Advocate as my representative—that is, the Holy Spirit—he will teach you everything and will remind you of everything I have told you.
So, my dear brothers and sisters, be strong and immovable. Always work enthusiastically for the Lord, for you know that nothing you do for the Lord is ever useless.
