Q: On what basis can we believe that Christianity is true and therefore other religions are not?
A: The truth of Christianity is predicated on the validity of the birth, life, death, and resurrection of Jesus of Nazareth. As Paul established, if Jesus did not rise from the dead, then Christianity is false, its hope barren, and we are lost in our sins (1 Corinthians 15:12-20). Among religions Christianity is distinctive for its insistence of the historical legitimacy of Jesus and His involvement in the “real world”; as Paul testified before Agrippa, the things surrounding Jesus of Nazareth and His Kingdom did not take place in a corner (Acts 26:26); Peter could depend on the common knowledge regarding Jesus and His actions among his fellow Israelites (Acts 2:22, 10:36-37). If the Apostles’ witness of the Risen Jesus is true, then He is the Christ, the Way, the Truth, and the Life, and we would be foolish to try to find hope in any other avenue (John 14:6, Acts 2:36).
We also may have confidence in Christianity as making the most sense of the world in which we live. We can recognize joy, majesty, and beauty, and yet also see misery, pain, suffering, and horror. The story of God in Christ, creating a good universe which was corrupted by sin and death, making man in His image, seeking after relational unity with God and each other, alienated by sin, and finding reconciliation and hope in Jesus’ death and resurrection, looking forward to life in the resurrection when sin and death are fully vanquished explains all these things well (Genesis 1:26-31, Romans 5:6-21, 8:17-25). Judaism and Islam tell a similar story but have no means to assess why some ought to be redeemed and others not beyond the capriciousness of God; Eastern religions tend to take the existence of evil for granted and find no hope to overcome it, yearning for spiritual bliss or enlightenment. Modern secularism cannot account for beauty, truth, or the search for meaning and order. Thus we have strong reasons for confidence in the truths made known to us by God in Christ.
