2 Timothy 3:16-17 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, thoroughly furnished unto all good works.
Here is a test of proving myself.
Genesis 4:15 And the Lord said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the Lord set a mark upon Cain, lest any finding him should kill him.
Ezekiel 9:4 And the Lord said unto him, Go through the midst of the city, through the midst of Jerusalem, and set a mark upon the foreheads of the men that sigh and that cry for all the abominations that be done in the midst thereof.
Revelations 13:16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
Is there a connection between these three scriptures as to the mark and meaningful revelation?
The effort that is to be put forth in answering this question needs to pass the smell test of 2 Timothy 3 stated above. In this I should begin with a series of questions about what I see in scripture.
Who profits? What proof is to be found? What thoughts need correction? Does it lead to righteousness?
That sounds like a lot to consider over a simple search of the scriptures. Hidden within those questions is a testing of self. Number one on that list is who profits. More often than not an honest search of our motivations in asking that question will reveal much. Is God to be glorified or me?
That answer alone will stop the search of many frivolous questions.
1 Timothy 1:4 Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do.
We need that self-test to know the difference.
