While I could be wrong, I believe the Bible leans towards Partial Cessationism (i.e. that the miraculous gifts given to believers has ceased and they were only for the early church) (See this thread
here). This does not mean that the believers do not have gifts of the Spirit, they are simply not gifts of healings, or prophecies, or speaking in tongues, etc. (i.e. miraculous gifts). I believe that the saints today are given gifts such as the gift of teaching, the gift of evangelism, etc. Miracles still happen, but they are a direct result of GOD doing so and not by the hand of a believer. No prophecy (new added holy words or visions) is given anymore.
In other words, I believe the baptism seen in the early church is not the same as we see today. I could be wrong, but I currently believe the baptism of the Holy Spirit happens when a person accepts Christ as their Savior with a godly sorrow over their sin. The baptism of the Holy Spirit is simply the receiving of the Spirit as a gift when a person accepts Christ.
If we are using 1 Corinthians 13:8-12 to come to the conclusion that the miraculous gifts of believers has ceased, we put ourselves in an awkward situation (which is not entirely bad). To say confidently they have ceased, you'd have to know when they have ceased. If we can't point to a specific time when they have, our stance is speculation at best. In my opinion, the best argument for partial cessation that points to a specific time would be at the Bible's completion. Would this be after John finished Revelation and his letters, the time of the Council of Nicea, or maybe even sometime after the invention of printing press where the Bible was made much more accessible?
When I read 1 Corinthians 13:8-12, I don't believe the point being made is that these gifts will cease sometime before we enter into eternal glory. Nor is there a specific time before this that we should look for where these miraculous gifts will pass away. I believe the point being made is the opposite, but with the focus being LOVE NEVER ENDS (incredible!). Hence, "we know in part and prophecy in part, but when the perfect comes, the partial will pass away." What is perfect that has come? Also, if prophecy and tongues are no longer today, what about knowledge? I read though your stance on what you believe the "perfect" is that has come. I respectively disagree with this stance. One issue I have with the "law" being what is the perfect that has come is that the law itself does not make perfection attainable. Furthermore, the law itself is not even fulfilled without Christ.
"For on the one hand, a former commandment is set aside because of its weakness and uselessness (for the law made nothing perfect); but on the other hand, a better hope is introduced, through which we draw near to God." - Hebrews 7:18-19
I see though that you shared Psalm 19:7, yet I must admit I am not sure how much of that verse we can apply to argue partial cessationism. My major question I am stuck wondering, what law is this talking about? The law that David was aware of at this time? Laws that were still yet to come, implying the law was not yet complete? Or could this simply be alluding to Christ who we know revives the soul? I am not trying to provide an answer here. I am simply pondering what is said in this verse. I feel as if in the argument of partial cessationism we'd have to say a law yet to come. Simply because if the perfect was already there, what need would there be for prophecy, tongues, and knowledge in the first place? Furthermore, why would Paul say "when the perfect comes" if the "perfect" was already present?
I have no choice but to believe the law is perfect, for the Bible says so. But I also have no choice to believe that the law made nothing perfect, because the Bible also says so. By just reading through Hebrews we can see that Jesus is far better than the law.
"There is therefore now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death. For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit." - Romans 8:1-4
Furthermore, I'd like to point out that it is entirely possible that we haven't seen miraculous gifts, prophecy, etc for say the last thousand years (I am not saying this is the case) but that doesn't have to necessarily mean they have ceased or passed away. Perhaps to our standard it could appear that way, but our standard doesn't form what is reality.
I also read in your stance that you said we don't read of any miraculous signs after Acts. This is no surprise since the Book of Acts is about the acts of the Apostles, whereas the epistles fall more inline with instruction and teaching. It may also come as a surprise that Paul possibly wrote a handful of his epistles during the events described in the Book of Acts. On the other hand though, we sure do read about prophecy after the events in Acts. In fact, there is an entire book about prophecy (Revelation). This brings me to my last point.
The final thing I would like to touch on that furthers the awkward situation partial cessationism runs into are the two witnesses in Revelation 11. We see that they prophesy, they can shut the sky allowing no rain to fall, they have the power to turn water into blood, and they have the power to strike the earth with every kind of plague. If you'd ask me, those are some pretty miraculous gifts. If I am to accept that prophecy has passed away, I am now in a weird state of confusion regarding these two witnesses. Let's pretend these two witnesses occurred during our lifetime and we have a lot of Christians today who believe prophecy has passed away. These same Christians are now in a very dangerous situation.
My stance on this is that prophecy, tongues, and miraculous gifts are still for today. I believe the "perfect" that Paul is speaking of in 1 Corinthians 13 is the Salvation we are waiting for in Jesus Christ. From what I gather, that seems to be the safest stance.
"But whatever gain I had, I counted as loss for the sake of Christ. Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith - that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, that by any means possible I may attain the resurrection from the dead. Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me his own. Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus. Let those of us who are mature think this way, and if in anything you think otherwise, God will reveal that also to you. Only let us hold true to what we have attained." - Philippians 3:7-16
"Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and the sea was no more. And I saw the holy city, new Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from the throne saying, "Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God. He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away."" - Revelation 21:1-4
This is where I confidently assert that prophecy, tongues, and knowing in part has ceased and passed away. But not love, for it was God's love that got us here in the first place.
