I would be interested in any reference from Scripture where either Jesus or Paul said directly that tongues, healing and prophecy were just for the Apostolic Age and were not to continue afterward. I'm not too interested in any quotes by 19th Century theologians who wrest 1 Corinthians 13:8 out of its proper context to words into Paul's mouth that he never said.
I take the definition of "sign" gifts that they are signs that the Kingdom of God is with us. I am not aware that the Kingdom of God has left us and gone somewhere, maybe on vacation. So, if the Kingdom of God is still with us, then the gifts that show the appropriate sign must also be with us still.
How ever you define it, thats make no different that this teaching began to become practice in Topeka and startet with the pentecostal movement in Azusa.
It was obviously finished in the first centurys. Because you can find in the churches in the second century an worldly life in the churches. And when Montanus ( around in the year 160 ) began His ministry and claimed from himself to be the counselour/ the Holy Spirit, speaking in tongues and prophecie rise again in his sect.
And believers in this time thought first that the Gifts which had stopped came again.
So many joined this sect, even Tertullian later.
And it is strange that out of the pentecostal and charismatic movements the Holy Spirit is not giving this sign gifts.
If the Holy Spirit is the One who gives the gifts. Then this is not a matter wether this is taught in the church ore not.
The believers in Acts were not taught before that they have to ask for the gift.
The Holy Spirit came and gave as sign the gift of speaking in tongues.
So if you would be right with your view, then every bornagain Christian would get this gift of speaking in tongues, independ what the churches would teach.
Btw it would not be nesassary that it would be taught, because it would be clear to understand from every believer. It would be normal for every Christian to speak in tongues. BUT this has not happend.
First in Topeka and Azusa then the believers were taught to pray and wait for the revealing of the Holy Spirit with the sign of speaking in tongues. Called today empowered with the Holy Spirit ore baptised with the Holy Spirit.
Nor in the NT nor in the time after the NT till to the beginning of the pentecostal movement Was this taught in the christian denominations we know.
Before 1900 of course we find speaking in tongues and prophecy and healings taught in cults like mormons and the new apostolic church.
You talk about the kingdom of God. The citiziens of this kingdom are at first the nation of Israel. Gods holy folk. As the prophecies from the OT which are not fulfilled till now,
will be fulfilled in Future.
If you would be right with your view, then that what you claime were openly to see everywhere. Nobody would have a reason to discuss about it.
Cessationism would not exist!
Thats the problem. What you are claiming is not the reality. Thats why we discuss.
