Yes. Walking with God is evidence of salvation and denotes a relationship with Him. In John 17:3, we read - And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent (which is an intimate, experiential knowledge, found only in a relationship). The term "know" implies intimate, experiential knowledge, through a relationship with Him and not merely theoretical knowledge.Do not play coy and do not twist my words.
I did not express the need for "flawless theology" nor "perfect theological knowledge".
How about this:
If good works are evidence of walking with God is walking with God evidence of salvation?
