these vanities
Acts 14:15
14:15 these vanities. “Vanities” refers to their worship of idols, representing mere personifications of natural forces as well as demonic spirits. It is vain to attribute true creative power, such as just evidenced in the instantaneous creation of perfect new legs for the hopeless crippled man to anything other than God. Only the true Creator, or those who call on Him and speak in His name, could do such things.
