How much assured for the thing of a historical fact

At the end, one thing I still have to study. The miracle first has a face as a historical fact. However, there is another aspect that miracle is drawn in relation to the figure of God, Moses, Elijah etc. in the Old Testament. The problem is the ratio between the two.
There are many places in the gospel that the figure of the Messiah (Savior), which the Old Testament shows as prophecy, is drawn just as it was realized in Jesus. There is a strong feeling of genuine enthusiasm for the Israelites who believe in the Old Testament of the Evangelicals to expect that Jesus is the Messiah as expected. For that reason, it is difficult to understand how much assured for the thing of a historical fact there. As a miracle of this kind, there are three things:

(1) The miracle that the Lord walks on the water
(2) The miracle that bread and fish increase
(3) The miracle that water changes to wine

There are also a few other things that have been written in relation to the Old Testament. In these miracles, it is still necessary to wait for the future research to see how much the ratio of the previous two faces is. Have to wait. It is still impossible to say the clear thing at the present time. The same could be said of the miracles that the Apostles had done in the early church. In other words, it comes to "Acts of the Apostles". In the current study of biblical studies, there is a large suspicion that it is a historical fact about these miracles in general. "The Acts of the Apostles" is not the gospel. However, this is the one that the author of the Luke Gospel wrote as an extension of the Gospel. When we compare the Miracles of Christ in the Gospel with the disciples of
"The Act of the Apostles", we are compelled to feel something complex. In any case, we have to wait for the Bible study in the future.
