being a double-minded man, unstable and restless in all his ways [in everything he thinks, feels, or decides].

And the seed whose fruit is righteousness (spiritual maturity) is sown in peace by those who make peace [by actively encouraging goodwill between individuals].

Therefore, confess your sins to one another [your false steps, your offenses], and pray for one another, that you may be healed and restored. The heartfelt and persistent prayer of a righteous man (believer) can accomplish much [when put into action and made effective by God—it is dynamic and can have tremendous power].
