Steve Ray has a list of more than 35 loaded Questions for "Bible Christians" (quotation marks his)(link to the whole list). I originally planned to respond to just 35 of them, but the series seems to have been of interest, so in this extension, I'm responding to three more numbered questions in his list, plus fourteen "bonus questions" that take the form "Where does the Bible say ... ." I'm trying to provide the answers in the same common format as the original series, for easy reference. This is number 17/17.
Where does the Bible . . .
. . . tell us Jesus Christ is of the same substance of Divinity as God the Father?
1) The use of the exact phrase of "substance of Divinity" is not found in Scripture.
2) There are many verses that prove that Jesus is God (in the sense of being the only Lord God). One of the more obvious examples is the following:
Jude 4 For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.
There are many treatises that examine this important Scriptural doctrine in much greater depth. I've tried to give a simple and concise answer, but many writers from ancient times down to modern times, have given much greater and more comprehensive exegeses of Scripture to thoroughly demonstrate this same truth.
