unfinished clay, Great that you're going to look at those passages again.

I'll have to look again but think it's either one such as "And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;" Mark 16:17 But let me know if you see it differently.

But you have to wonder what they would be like if they never came. Remember years ago when judges would sentence certain folks to attend church for a specific number of weeks/months. I've heard testimonies from some of them and how it changed their lives.

You may be referring just to the tongues question but there's nothing wrong with asking Yahweh that question in regards to everything. Know it makes some feel uneasy but we need to take a few minutes and wait on His direction.
In regards to repentance or manifestations emphasis, Yeshua said if you don't believe in me, believe the signs and wonders - then you'll get the connection "If I do not the works of my Father, believe me not. But if I do, though ye believe not me, believe the works: that ye may know, and believe, that the Father is in me, and I in him."
John 10:37-38
