another, that you may be healed. The prayer of a righteous person has
great power as it is working. (ESV James 5:16)
I was surprised to find that the NASB says "The effective prayer of a
righteous man can accomplish much."
The word translated effective in Greek is:
From G1756; to be active, efficient: - do, (be) effectual (fervent),
be mighty in, shew forth self, work (effectually in).
This looks like its saying, "The "energized and fervent" prayer of a
righteous man can accomplish much. That sounds more motivating than
"effective". It's harder for me to know what praying effective looks
like. If someone asked me to pray with energy and fervency, this I
could picture and be motivated to try.
