Jesus walked upon this earth. He was born and He died. How do we know this? We know it for three reasons.
The Personal Witness Of The Saints
Acts 10:39-41 says, "And we are witnesses of all things which He did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree: Him God raised up the third day, and showed Him openly; not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with Him after He rose from the dead."
Over 500 people saw Jesus after His death and most of these died because of their belief. Let me say, a man may live for a lie, but would he die for one?
The Prophetic Witness Of The Scriptures
Acts 10:43 says, "To Him give all the prophets witness, that through His name whosoever believes in Him shall receive remission of sins." When the writer says "all the prophets," he is talking about the prophets from Genesis to Malachi (remember, the New Testament hadn't been written yet).
In Genesis 3, we read about the One who will bruise the head of the serpent. In Genesis 12, He is going to come from the seed of Abraham. In Genesis 22, we read about the sacrifice of Isaac on the very mountain where Jesus was later crucified! The entire book of Leviticus is filled with pictures of blood-atoning sacrifices for sin. You'll read about the prophetic crucifixion of Jesus in Psalm 22. In Micah 5:2, it is told clearly that Jesus will be born in Bethlehem.
I could go on and on, but the bottom line is: there is but one plan of salvation in all the Bible and that is through the blood-atoning sacrifice of the God-Man, Jesus Christ.
The Powerful Witness Of The Spirit
The Holy Spirit takes the Word of God and says, "Amen. It is written. It is truth." I thank God that I don't have to try and talk you into believing Jesus. If there's anything I can talk you into, there's someone who can talk you right out of it!
1 John 5:9-11 says, "If we receive the witness of men, the witness of God is greater: for this is the witness of God which He has testified of His Son. He that believes on the Son of God has the witness in himself: he that believes not God has made him a liar; because he believes not the record that God gave of his Son. And this is the record, that God has given to us eternal life, and this life is in His Son."
