Does the Bible talk about other gods?

The God of the Bible is referred to as the true and living God (Jer 10:10, 1 Thes 1:9) distinguishing Him from false gods which are commonly referred to as idols (1 Chron 16:26). The true God has this to say about false gods:

"Do men make their own gods? Yes, but they are not really gods!" (Jer 16:20)

Most Bible translations use a lower case "g" to signify when talking about those things that humans treat like gods (masters), yet don't actually have God's attributes - omniscience (all knowing), omnipresence (everywhere at once), and omnipotence (ultimately powerful). Satan is even referred to in the Bible as the "god of this world" (2 Cor 4:4), because the majority of humans have either intentionally or unintentionally allowed him to be the master of their life. There is nothing more sad or more foolish than humans investing their love and allegiance in something that cannot give them life in return. However, from the beginning of time, humans have created false gods and invented religions to suit their selfish desires, in an effort to maintain control of their own life and avoid dealing with their sin. They make themselves feel good by measuring their holiness according to things like: how many times a day they bow down, how many sacrifices they make, how often they visit so-called sacred sites, how many good deeds they accomplish, how long their robes are, how long their prayers are or how long their titles are. In this age, most of the people in the world don't have idols made of wood or silver that they worship...but, ask yourself this: What is it that most people love more than anything? What do they devote the majority of their time, energy and effection to? What is it that they always want more of? Anything you love more than God is a false god, an idol.

"No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money." (Luke 16:13)

Wherever your treasure is, that's where your heart will be. (Matt 6:21)
