How do we know that there is one God?

The doctrine of one God is a central tenet of historic Reformed theology. The Bible clearly asserts this in passages like Ephesians 4:6, which states, 'One God and Father of all, who is above all, and through all, and in you all.' This highlights the sovereignty of God over all creation, as there are many false gods and religions in the world, but they are all mere man-made inventions. In the context of our faith, recognizing one God helps us understand our relationship with Him as the source of all things.

Moreover, the exclusivity of the true God contrasts sharply with the plethora of so-called deities that people often worship. Throughout history, idols have represented all that is opposed to the glory of the true God. The confession that 'there is but one God' also leads believers to a profound appreciation of His attributes and His eternal existence, which is not contingent upon human understanding or definitions. The assertion of one God thus serves as the foundation upon which our faith is built, leading us to worship and honor Him above all else.
