it is evidenced by those that have done it.
Essentially you are suggesting. Should trust any man. I am suggesting I rather trust Jesus. Honestly, I do not think your approach will survive. But you are welcome to try. Only, if you think deceit is sufficient, it still appears as deceit. Likewise for speculation.
OK. I really had to do a 180 degree when I did it. But I was not atheist. I was anti Christian, aggressively opposed to it. Vocally and publicly. Then I was confronted: if you are such an atheist, read x book. Well I had to admit, I was not atheist. But why then, if I did want to praise God, did I not know Him like they did. Then I struggled with my pride all night, then I askd them to show me proof of God. The verse they gave me made the penny drop. Then I read the bible form them first time in years and years and every thing I read made sense like nothing before. The whole process of that discovery and decision took three weeks. I did not set out for it and I did not I know it was coming. But I know that I did beg Him to give me the knowledge of the truth, and He granted it in the exadt same moment I asked for it and He personally taught me for two weeks following. I know how real He is. I do not tolerate malarki.
