I am sorry I missed this thread as the issue is close to my heart.
I think poor teaching is the main reason.
Also the modern mega churches need action to attract followers. The object of the exercise then is to 'move in the gifts' this provides visual stimulation and draws a crowd.
This is a mistake.
Folks must learn to hear Him first.
Jesus could do nothing without seeing what the father was doing first.
Are we greater than Jesus ???
NO.
It comes back to a fear of total commitment which I believe is common.
The harvest is ripe and the workers are few - folks need to understand that the gifts operate in the 'edge of the kingdom' on the streets and the marketplace where if He doesn't show up your toast.
So an over emphasis of the gifts is problematic because we simply read "confess your sins one to another and pray for one another that you may be healed". No mention of gifts and a clear directive to all as a matter of obedience.
Another factor is that the faith levels were high in the early church because we are speaking of those who saw the resurrection first hand.
What we need today then is life changing encounters with Him - how many today have 'seen' Him in one way or the other? This is where faith comes from.
I remember a vision I had years ago - throngs of believers walking in the same direction - amazing singing overhead - and on the side of the crowd folks saying "this is the way to walk" and I knew they didn't know but were blind guides. Looking in the distance I could see there was a common destination - it was the cross.
Just a few thoughts.
These are good thoughts, and I give a hearty AMEN to the bit about mega-churches. Those places are cesspools of unbelief laden with tricks and gimmicks to pad some person's heavenly resume.
I definitely believe that our amount of faith has an effect on this. Faith comes from hearing and hearing by the word of God. So there is definitely an element here of how close we are to God that correlates to our walking in the Spirit's power. Time spent reading/studying the scriptures and in prayer (fasting included).
Something new that has come to mind since posting this is a rather intriguing element to this that fascinates me.
The western world is a very logical place. We are well educated for the most part, and base a lot of our experiences on our physical senses. I've heard that in areas in the Middle East, Africa, and China that miracles are a regular thing in the church. Which is interesting for another reason to be explained in a second. But those areas for the most part are not as educated and logical as the West is. So perhaps there's an element where we cannot experience deep things in the Spirit because we base a lot of our experiences on our mind, not the Spirit.
Also, church father testified that miracles and gifts were still in operation well into the 3rd century, even the early 4th century. In 312, Constantine made Christianity the official religion of Rome and I truly believe at that moment, when the church traded message for security, is when the Spirit withdrew a good bit of power from the church as a whole. We traded our True Shepherd for a hireling. When you read in scripture about power miracles, they are normally in connection with someone who has or is willing to endure persecution for the gospel. Not that we should seek persecution, or rebel against our governments, but it really feels like in our compromising the message for security, we lose out on some of the power of the Spirit. This is why I feel those in the Middle East, China, etc probably do still see great miracles. They experience persecution on a daily basis, even still.
So it's perhaps a combination of things.
Now what does that mean for us?
Again, not espousing that we should be rebellious to our governing bodies. But I do believe we need to be honest with people about what the gospel is, not watered down like many mega churches and such preach. It's not a popular message, but a necessary one. Repent and be baptized calling on the name of Jesus and you will receive the gift of the Holy Spirit. As for advancing past our logical, physical senses based existence? Just start walking in faith a bit more. When Jesus and them healed, they said get up and walk, not let me pray, "Father please heal in the name of Jesus." They didn't see people as they were, they saw them as God wanted them to be and commanded them forth as such.
Just some thoughts, but thank you for sharing!
