Limited to Acts 24:25; Gal. 5:23; 2 Pet. 1:6, the Greek noun “enkrateia” meant “self-control” or “temperance.”
“Considering the great importance given to the theme of self-control in Greco-Roman ethics, one is surprised by the relatively little attention paid to it in the NT” (Silva, 1:84). For the apostles, the “Christian life-style is not a matter of an autonomous ethic, but is rather to be understood only as the response to the prior gift of salvation through God himself” (ibid).
