How do we know Christ's resurrection and ascension are true?

The resurrection and ascension of Christ are foundational truths affirmed by the testimonies of multiple eyewitnesses. In Acts 1:3, Luke notes that Jesus presented Himself alive to the disciples after His suffering by many infallible proofs for forty days. This period of post-resurrection appearances is vital in establishing the reality of the resurrection. The ascension was witnessed by His apostles, further solidifying this truth. The credibility of the resurrection and ascension is also supported by the transformation of the disciples, who went from fearful individuals to bold proclaimers of the Gospel, even unto death, which is a testament to their conviction in the truth they witnessed.
