How can we have faith in Jesus if we haven't seen Him?

The absence of physical evidence of Jesus does not negate the reality of faith; rather, faith is grounded in the testimony of Scripture. Romans 10:17 notes that 'faith comes by hearing, and hearing by the word of God.' True faith relies not on personal sight but on the truth conveyed through the gospel. Believers are called to trust in the promises of God and the historical act of Christ's redemptive work, which stands as the basis for faith. The Spirit, as indicated in John 15, plays a crucial role in guiding believers to understand this truth, enabling them to have faith in the unseen reality of Christ as revealed in the Scriptures.
