No you are not right.
That applies to majority of the Christians today. In the 1st century, the apostles and disciples worked signs and wonders so that people may believe in the Gospel because their mandate was to spread the gospel to all nations before the end times( End times simply means antichrist's reign). They would do all signs and wonders as long as the antichrist was not in the scene and for that reason the antichrist was being held back so that they finish their testimony for they are the two witnesses being talked about.
As soon as they finish their testimony, the antichrist begins to reign and the first order of event was to pursue the two witnesses and kill them. Then the signs and wonders cease from that moment on because the antichrist comes with fake sign and wonders. God is not a God of confusion that a genuine sign there and a fake one here so that people are confused and they can get an excuse- from that moment on, all signs and wonders are fake. The Holy spirit operates at an individual level- if i'm sick and it is the will of God that i'm healed, He heals me from within and not someone laying their hands on me.
2 Thess 2:
5 Don’t you remember that when I was with you I used to tell you these things?
6And now you know what is holding him back, so that he may be revealed at the proper time.
7For the secret power of lawlessness is already at work; but the one who now holds it back will continue to do so till he is taken out of the way.
8And then the lawless one will be revealed, whom the Lord Jesus will overthrow with the breath of his mouth and destroy by the splendor of his coming.
9The coming of the lawless one will be in accordance with how Satan works. He will use all sorts of displays of power through signs and wonders that serve the lie, 10and all the ways that wickedness deceives those who are perishing. They perish because they refused to love the truth and so be saved.
11For this reason God sends them a powerful delusion so that they will believe the lie
12and so that all will be condemned who have not believed the truth but have delighted in wickedness.
Rev 13:
11 Then I saw a second beast, coming out of the earth. It had two horns like a lamb, but it spoke like a dragon.
12It exercised all the authority of the first beast on its behalf, and made the earth and its inhabitants worship the first beast, whose fatal wound had been healed.
13And it performed great signs, even causing fire to come down from heaven to the earth in full view of the people. 14Because of the signs it was given power to perform on behalf of the first beast, it deceived the inhabitants of the earth
So those people that will be told "i never knew you.." are non other than these so many people that have call themselves christians doing every kind of sign (healing/speaking in tongues/prophesying etc). They truly believe that all these is from God but they fail to note the times/season we are in.
The kingdom of God doesn't come with observable signs and it was also said that the first shall be the last and the last be the first.
All that is asked for from God's people is patience & perseverance, humility plays a big role but most importantly, the Holy spirit is to give us understanding and not signs. Only a perverse generation seeks after signs.
