How do we know Jesus's resurrection is true?

The resurrection of Jesus Christ is a cornerstone of Christian faith, firmly established through numerous eyewitness testimonies. The disciples, who were once fearful and confused following Jesus's crucifixion, dramatically transformed into bold witnesses after encountering the risen Christ. In 1 John 1:1, John asserts the authenticity of their experience, declaring that they heard, saw, and even touched the Word of life. This direct witness, coupled with the radical changes in the apostles' lives—going from despair to proclaiming the resurrection—is powerful evidence of the truth that Jesus rose from the dead. Furthermore, the resurrection provides a foundation for our faith and assurance of salvation, as it confirms Jesus's authority over sin and death.
