Biōtikos (βιωτικός) is an adjective meaning "pertaining to life" — specifically to ordinary earthly life and its affairs. It appears twice in the New Testament: Luke 21:34, where Jesus warns against hearts weighed down by "dissipation, drunkenness and the anxieties of life," and 1 Corinthians 6:3–4, where Paul references "matters pertaining to this life" that are brought before secular courts.
Jesus' warning against the "cares of this life" (merimnas biōtikas, Luke 21:34) reveals that the greatest threat to spiritual readiness is not dramatic sin but mundane distraction. The day of the Lord will come "as a snare" on those whose hearts are weighted down by everyday worries and pleasures. Paul's use in 1 Corinthians 6 shows that biōtika — earthly disputes about money, property, and relationships — were consuming the Corinthian church's energy. Both passages call believers to keep eternal perspective while navigating temporal affairs.
