17 And these signs shall follow them that believe; In my name shall they cast out devils; they shall speak with new tongues;
18 They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
"The Spirit of the Lord is on me, because he has anointed me to proclaim good news to the poor. He has sent me to proclaim freedom for the prisoners and recovery of sight for the blind, to set the oppressed free,
21Again Jesus said, “Peace be with you! As the Father has sent me, I am sending you.”
22And with that he breathed on them and said, “Receive the Holy Spirit.
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
49And behold, I am sending the promise of my Father upon you. But stay in the city until you are clothed with power from on high.”
But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.”
1And when the day of Pentecost was fully come, they were all with one accord in one place.
2And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
3And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.
4And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
17And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:
18And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy:
1Now concerning spiritual
gifts, brethren, I would not have you ignorant.
4Now there are diversities of gifts, but the same Spirit.
5And there are differences of administrations, but the same Lord.
6And there are diversities of operations, but it is the same God which worketh all in all.
7But the manifestation of the Spirit is given to every man to profit withal.
8For to one is given by the Spirit the word of wisdom; to another the word of knowledge by the same Spirit;
9To another faith by the same Spirit; to another the gifts of healing by the same Spirit;
10To another the working of miracles; to another prophecy; to another discerning of spirits; to another
divers kinds of tongues; to another the interpretation of tongues:
11But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
Now 1 Corinthians was written 20 years after Paul's conversion and he is teaching them about how they all have been given gifts by the Holy Spirit to benefit the body of Christ among which are what you call "sign gifts" but what the scriptures simply call spiritual gifts.
They had not ceased and the only mention of them every ceasing was when he mentions the return of Christ or our going to be with Him, "That which is perfect is come" not the writing of the book of Revelation but the day when we will see him face to face (1 Cor 13) and until then TRUE LOVE is shown by operating in the gifts of the Spirit in a motivation of Love.
Your denial of the Holy Spirit gifts disqualifies you from being able to teach since it is one of the gifts. No one really wants to listen to someone who does not depend on the Spiritual gift of teaching. Otherwise it is just vain babbling of the erroneous interpretations such as "the gifts have ceases" being a prime example.
