'True God' in the Bible

Now eternal life means knowing you as the only true God and knowing Jesus your messenger as Christ.

So he moved into the house of a pagan named Titus Justus, who worshiped the true God; his house was next to the synagogue.

But at that former time, as you did not know the true God, you were slaves to gods that do not really exist,

For the people themselves tell us what a welcome you gave us, and how you turned from idols to the true God, to serve the God who lives on and is real,

And we know that the Son of God has come, and has given us insight to recognize the True One; and we are in union with the True One through His Son, Jesus Christ. He is the true God and eternal life.
