Thats not my job to prove truth to anyone, thats the Spirits Job, He sanctifies unto the belief of the Truth at His will 2 Thess 2:13
13 But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth:
Now wonder if people are under the Judgment of God, and He has sent them a strong delusion to believe a lie 2 Thess 2:11-12
11 And for this cause God shall send them strong delusion, that they should believe a lie:
12 That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
Now how is it my Job and in my ability to prove truth to them?
