"miss the voice of the spirit"
The Lord is fully capable of communicating with us. He is not an ant with a tiny voice that is very hard to hear. The Lord spoke through audible voices, burning bushes, angels and other means. I seriously doubt that the church has "miss the voice of the spirit" for over 2000yrs.
"we are disobedient"
Who wouldn't want to heal the sick, cast out demons and raise the death. This would save us a great deal of heartache in our lives. Again, I don't think that %99.9 of the church is in direct defiance of the word. We simply don't do this because we can't not because we won't.
"lack of understanding jewish things"
This is not a requirement of gentile believers. Paul preached against this. I can eat pork, go uncircumsised and still be in right standing with God because of the Blood of Jesus, not Jewish customs/things.
these are just more excuses to deny reality. The reality is very few experience "abundant life" here on the planet and very few perform miraculous signs and wonders.
Either Jesus was talking about heaven or he wasn't there is no in between because of this or that reason. Do not add to the word, John 10:10 has absolutely no conditional statements attached to it.
I have come that they might have life and that they might have it more abundantly if.................
