In addition to the repeated Gospel recording of Christ’s Resurrection, which other two Scriptures are key and critical to the cornerstone of the Christian faith—Christ’s crucifixion?
After Christ’s Resurrection from the dead, Christ “appeared to His disciples in many convincing proofs—over a period of 40 days!! (Acts 1:3).
Why did/does Christ so strongly use the concept “witnesses?”
At the point of Christ’s crucifixion event and Resurrection—and immediately thereafter and repeatedly—the emphasis among Christ’s followers and even Christ Himself, was this: witnesses; witnesses; witnesses. Whenever you use the word “witness,” you are immediately talking also about proof! Even today, if Christ rose from the dead, the most convincing proof would be many witnesses.
