Is being slain in the spirit, or is speaking in an unknown tongues, or is dancing in the spirit, etc., from God or of God?
I have spoken in unknown tongues! I have danced onto the Lord! I have run for the Lord. All of these over many years in me have been of God and in accord with His Spirit in me.
I have been healed of physical illnesses by the Lord!
In my dreams I have danced on the ceiling for the Lord in the Spirit.
In my dreams I have been lifted up and flown before God as an eagles flies in the Spirit!
I have never, that I recall, been 'slain in the spirit'!
"Are all apostles? are all prophets? are all teachers? are all workers of miracles?
Have all the gifts of healing? do all speak with tongues? do all interpret?" I Cor 12:29-30
The answers to each of Paul's questions are, "No", not all!
Because I haven't been slain in the Spirit of God, does that mean that no one else has?
Whatever we need to do, if we follow the lead of the God's Spirit, will we not do it?
Whatever we do not know, if we have a need to know, will we come to know it by following the Spirit of God?
"And now I say unto you, Refrain from these men, and let them alone: for if this counsel or this work be of men, it will come to nought:
But if it be of God, ye cannot overthrow it; lest haply ye be found even to fight against God." Acts 5:38-39
There are, indeed, spirits ready to lead us along pathways away from God, but, if we are trusting the Lord, where is the danger? How can there be danger for anyone who is on the Lord’s side?
“What shall we then say to these things? If God be for us, who can be against us?” Rom 8:31
If are too cautious in our walk with God, we may quench the Spirit of God that desires to work in us to make us what He wants us to be. We, alone, cannot make ourselves into anything good, but God in us can! If we decide in our own mind to not involve ourselves in what seems to us to be nonsense, we may find ourselves in the position of the man who received one talent...
"Take therefore the talent from him, and give it unto him which hath ten talents.
For unto every one that hath shall be given, and he shall have abundance: but from him that hath not shall be taken away even that which he hath.
And cast ye the unprofitable servant into outer darkness : there shall be weeping and gnashing of teeth." Matt 25:28-30
Or... then again we may find ourselves where Naaman the Syrian would have been if he had insisted on following his own mind instead of obeying the the seemingly nonsensical instructions he had received from the prophet Elisha!
"But Naaman was wroth, and went away, and said, Behold, I thought, He will surely come out to me, and stand, and call on the name of the LORD his God, and strike his hand over the place, and recover the leper.
Are not Abana and Pharpar, rivers of Damascus, better than all the waters of Israel? may I not wash in them, and be clean? So he turned and went away in a rage.
And his servants came near, and spake unto him, and said, My father, if the prophet had bid thee do some great thing, wouldest thou not have done it? how much rather then, when he saith to thee, Wash, and be clean?
Then went he down, and dipped himself seven times in Jordan, according to the saying of the man of God: and his flesh came again like unto the flesh of a little child, and he was clean." II KIngs 5:11-14
"Rejoice evermore.
Pray without ceasing.
In every thing give thanks: for this is the will of God in Christ Jesus concerning you.
Quench not the Spirit." I Thess 5:16-19
