Is there any evidence for the Ressurection of Jesus Christ?
That can be hard for some people to accept that Jesus resurrected from the grave, because the Bible said certain people said it was true, for they say how do we know it is true.
Which the Bible says we should believe the account of God that He gave us His Son.
So it matters if a person believes in the Holy Bible, and the account of God concerning His Son in that Bible, for if they accept the Holy Bible, and the God of the Bible, as true, then they should accept the account God gave of His Son, and if they believe the God of the Bible then it is child's play for Him to resurrect the dead, which Jesus said nothing is impossible with God, who understands the working of physical matter.
God said that He identifies Himself as the one true God by showing us the end from the beginning, prophesy, which He said no other religion, or person, will be able to do that, which He told us the whole history of mankind, and all the kingdoms that would come up one after the other.
Which God told us what is going on today with the world, and what will come to pass shortly, which the next kingdom to come is the ten horn kingdom, the world split in to ten section with a leader in each section, as the nations come together and say Peace and safety as they try to establish peace on earth.
Daniel did not understand what was told him in the book of Daniel, which he was told not to worry about it, for he could not understand it, but to go his way for the book is sealed unto the time of the end, many shall run to and fro, advanced travel, and knowledge shall be increased, advanced technology, which then the saints would be able to see, hear, and know, what is going on in the world where the nations will come together and rebel against God.
Which the Bible warns the saints about the new age movement that shall happen at the latter times, the last days of the last days, and close to Jesus getting His people off this earth, and then putting the wicked down, and the new age movement's false interpretation of the Bible based on the occult, and evolution, and people can still evolve, and will lead the world that does not love God to follow the New Age Christ in Revelation 13, and when they do God will get His people off the earth, and then fight the world that rebelled against Him.
Which the saints can know about what the world is doing, so it is the time of the end, and the new age movement is here, which is the beginning of the end for those who do not love God.
God told us prophesy to identify Himself as the one true God, and His word true, and told us everything that would occur at this time, and of automobiles, and jets, like birds flying, when Israel took control of Jerusalem in the 6 day war, 1967, and the bringing of the Jews back to their land, and making them a nation again, among other things.
So the thing that has to be done with some people is to cause them to understand that the Bible is true, and the God of the Bible is true, for then they should believe the account that God gave of His Son, which if He created everything it is a simple thing to raise a person from the dead.
But do you mean from a source outside the Bible proving the resurrection is true, but I still wanted to point that out above for those that do not believe the account of the Son resurrecting from the dead.
