But if it be of God, ye cannot overthrow it; lest haply ye be found even to fight against God. Acts 5:39.
We can see what evidence was given the priests and rulers and how firmly they resisted the Spirit of God. Those who claim superior wisdom and piety may make most terrible and (to themselves) fatal mistakes if they allow their minds to be molded by another power, and pursue a course in resistance to the Holy Spirit. The Lord Jesus, represented by the Holy Spirit, was in the presence of that assembly [of priests trying the apostles], but they did not discern Him. For a moment they had felt the conviction of the Spirit, that Jesus was the Son of God, but they stifled conscience and became blinder and more hardened than before. Even after they had crucified the Saviour, God in His mercy had sent them ... another call to repentance, even in the terrible charge brought against them by the apostles, that they had killed the Prince of life.
It was not alone the sin of putting to death the Son of God that cut them off from salvation, but their persistence in rejecting light and the conviction of the Holy Spirit. The spirit that works in the children of disobedience worked in them, leading them to abuse the men through whom God was giving a testimony to them. The malignity of rebellion reappeared and was intensified in every successive act of resistance against God's servants and the message He had given them to declare.
Every act of resistance makes it harder to yield. Being the leaders of the people, the priests and rulers felt it incumbent on them to defend the course they had taken. They must prove that they had been in the right. Having committed themselves in opposition to Christ, every act of resistance became an additional incentive to persist in the same path. The events of their past career of opposition were as precious treasures to be jealously guarded. And the hatred and malignity that inspired those acts was concentrated against the apostles.
The Spirit of God revealed its presence unto those who, irrespective of the fear or favor of the public, declared the truth that had been committed to them. Under the demonstration of the Holy Spirit's power, the Jews saw their guilt in refusing the evidence that God had sent; but they would not yield their wicked resistance. Their obstinacy became more and more determined, and worked the ruin of their souls. It was not that they could not yield, but that they could and would not.—Letter 38, 1896.
