How do we know that the God we worship is the true God?
Answered in 1 source
We know the God we worship is the true God through revelation in Scripture, the gospel, and the historical reality of Jesus Christ's resurrection.
The identification of the true God relies on the revelation of God in Scripture and the person of Jesus Christ. Paul’s sermon on Mars Hill in Acts 17 illustrates this by contrasting the true God, who created the world and is unconfined by human-made temples, with the false gods of the Athenians. Moreover, the resurrection of Jesus Christ serves as a definitive assurance of God’s power and authority. This historic event attests to the truth of the gospel, confirming Jesus as the Christ, and calls all people to repentance. Thus, understanding God through His revelation is foundational to discerning truth from error.
