Does God extend that means to understand towards all sinners than?You're projecting someone else's beliefs onto me. Nowhere in this thread have I described my stance on salvation, except to say that natural man, under the influence of the Holy Spirit, can understand the Gospel.
I notice that you continually avoid addressing my point that 1 Cor. 2 is describing deeper spiritual things as being not received by the natural man and these deeper things that are not understood is not the gospel.
