G1756–ἐνεργής, ἐναργής–energēs, enargēs

for a door to me hath been opened -- great and effectual -- and withstanders `are' many.

ἐνεργὴς energēs “productive”

that the fellowship of thy faith may become working in the full knowledge of every good thing that `is' in you toward Christ Jesus;

ἐνεργὴς energēs “effective”

ἐνεργὴς energēs “active”
