The reality is; currently, there's no genuine tongues/prophesies/miracles/healing that people claim here and there. I'm not saying that they ceased entirely but the spirit of God works within individuals and never for public show as was the case in 1st century.
Cessation is not just an assertion but a deeper understanding of times and seasons and the reason the manifestation of all these gifts had to change.
IMO, the root to cessation would be this prophesy:
Jer 31:
31“The days are coming,” declares the Lord,
“when I will make a new covenant
with the people of Israel
and with the people of Judah.
32It will not be like the covenant
I made with their ancestors
when I took them by the hand
to lead them out of Egypt,
because they broke my covenant,
though I was a husband to
d them,
e ”
declares the Lord.
33“This is the covenant I will make with the people of Israel
after that time,” declares the Lord.
“I will put my law in their minds
and write it on their hearts.
I will be their God,
and they will be my people.
34No longer will they teach their neighbor,
or say to one another, ‘Know the Lord,’
because they will all know me,
from the least of them to the greatest,”
As soon as the new covenant is ratified, there is no such thing as evangelists/apostles/ healers/prophets/miracle workers/tongue speakers. All these thing had their time which is now long gone but many will be disappointed. Now God works within our hearts individually- i can say i'm healed, i don't need people to lay hands on me/ i have understanding when i read the bible, i don't need a preacher to give me their version of understanding. This is how it is supposed to be in the new covenant.
Again, many will be disappointed. Many means many.
Matt 7:
21“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven.
22Many will say to me on that day,
‘Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?’
23Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’
