Reference James 1:8
Lk 16:13 No servant can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money.
Although this passage from Luke’s Gospel is talking about money, the principle of double-mindedness is universal. Jesus says you can’t have divided loyalty.
Double-minded: The Greek dipsuchos is used only twice in scripture and both times by James. It literally means double-minded, uncertain, doubting, wavering, and divided interest.
Unstable: The Greek akatastatos means unstable, inconstant, and restless.
