and continually recalling before our God and Father your work of faith, your labor of love, and your enduring hope in our Lord Jesus Christ. — 1 Thessalonians 1:3

"your work of faith" — Paul connects faith, labor, and hope. The work of faith is to believe in the one God sent. Only faith working through love counts. We're his workmanship created for good works. Faith produces something because it's alive.
