In the single most significant event in all of history, the Lord Jesus Christ rose from the dead three days after He was crucified. This made the salvation of all believers totally and permanently secure. Nothing and no one can ever change that. Satan, sin, and death are defeated foes that are only temporarily present. They cannot ultimately do us any harm.
The skeptics often claim the Resurrection is a hoax, but it is, in fact, a historical fact of absolute status. It is more provable and demonstrable, even outside of the realm of faith, than a very large percentage of other historical facts. This single fact vindicates the person and work of the Lord Jesus Christ. It proves who He is, and it proves what He did. It proves the Bible to be true from cover to cover, from the literal creation of the universe and all it contains, to the ultimate judgment of all of all humans and the culmination of all temporal things into eternity future.
This fact of the Resurrection totally validates the sinfulness of man, the Gospel of Jesus Christ, and the need in the heart of all people for the salvation that only He can provide. It makes foolish all the arguments of ungodly men and challenges them with the haunting question of the Roman Governor, Pilate, who asked the crowd, “What then shall I do with Jesus who is called Christ?” (Matthew 27:22, NKJV). Every human being must personally answer this question. There will be no exceptions.
