Demonstrate (1732) (endeixis from endeíknumi = show forth <> en = in, to + deíknumi = expose to eyes and give proof, make known by visual, auditory, or linguistic means) means a pointing out (particularly with the finger). It is something that points to or serves as an indicator of something else and hence is synonymous with a sign, an indication, evidence, verification. It describes the means by which one knows that something is a fact. It is something that compels acceptance of something mentally or emotionally and thus serves as a demonstration or a proof. In secular Greek endeixis meant a pointing out and was used as a legal term, meaning a laying out of information against one who discharged public functions for which he was legally disqualified. Endeixis is found 4 times in the NT (see below), not in the Septuagint = LXX Romans 3:25 whom God displayed publicly as a propitiation in His blood through faith. This was to demonstrate His righteousness, because in the forbearance of God He passed over the sins previously committed; Romans 3:26 for the demonstration, I say, of His righteousness at the present time, that He might be just and the justifier of the one who has faith in Jesus. 2Cor 8:24 Therefore openly before the churches show them the proof of your love and of our reason for boasting about you. Philippians 1:28 (note) in no way alarmed by your opponents-- which is a sign of destruction for them, but of salvation for you, and that too, from God.
