How do we know that Christ is the only way to the Father?

The doctrine that Christ is the sole means of salvation is rooted in several biblical texts. Acts 4:12 states, 'There is salvation in no one else, for there is no other name under heaven given among men by which we must be saved.' This verse encapsulates the exclusivity of Christ's role in salvation. Moreover, throughout the Bible, patriarchs, prophets, and apostles recognized no other means to access God, as Jesus himself indicates in John 8:56 where Abraham rejoiced at His coming. The entirety of Scripture reinforces that any attempt to seek God outside of Christ is futile, denouncing those who preach other ways as cursed (Galatians 1:8). Hence, the certainty of Christ as the only way is firmly established in both His claims and the witness of biblical history.
