There are many such people, who not only will not admit the possibility of miracles today, or at any time since the apostolic era, but equally reject the possibility of demon-possession today. They are dismissing it all as psychological. They will not grant that it is possible for a person to be demon-possessed today. They admit, of course, that it happened in New Testament times; but, they say, not now. I am not imagining all this. I have been involved in discussions about it, and I know that this is their standpoint. They will not accept the possibility of demon-possession today. It is all explained in terms of psychology. This is as if to say, you see, that because, on their understanding of it, God had decided at the end of the apostolic era that He would not interfere any more in a miraculous manner, the devil also very kindly and very politely said, 'Well, I will not act either.' That is what it comes to. You see, the thing is monstrous and ridiculous. In other words, these men have worked themselves into a theoretical and academical theological position in which God is not allowed to act, and the demons are not allowed to act; there is no spiritual activity.
What is being taught in Christendom today is this, that since we have got the New Testament canon, since we have got the Word now, we do not need these direct interventions, we do not need God to speak to us directly, as He spoke to Abraham and to Isaac and to Jacob and these patriarchs. We have got the Word now! Is this superior to the direct speech of God? I think we are mad! This teaching would have us believe that we do not need this direct contact with God now, and that all that has come to an end since the formation of the New Testament canon.
Does this mean that because we have got it all recorded, (the Lord Jesus) has stopped acting? I suggest that that is to deny the message of the Scriptures. He goes on acting. He has not stopped acting. As He did not stop when He rose from the dead, and He did not stop when the Spirit was sent, still less has He stopped because we have got the New Testament canon.
Do we individually and personally really believe that God still acts, can act and will act - in individuals, in groups of individuals, in churches, localities, perhaps even in countries? Do we believe that He is as capable of doing that today as He was in ancient times - the Old Testament, the New Testament times, the book of Acts, Protestant Reformation, Puritans, Methodist Awakening, 1859, 1904-5? Do we really believe that He can still do it? You see, it is ultimately what you believe about God. If He is the great Jehovah - I am that I am, I am that I shall be, unchanged, unchanging, unchangeable, the everlasting and eternal God - well, He can still do it. And I believe He is saying to us. 'Try Me. Prove Me. Cast your all upon Me. Go on until I have given you the proof you desire.' (Malachi 3:10)
