I'll Think About God Later.

The apostle Paul had been arrested and thrown in prison. The leaders of the Jews wanted him dead, but Paul was a Roman citizen so the Romans took charge. One day he was brought before Felix, the procruator of Judea.

"Some days later Felix arrived with Drusilla, his wife who was a Jewess, and sent for Paul and heard him speak about faith in Christ Jesus." Acts 24:24

What a wonderful opportunity for Paul to lift up the life and death of Jesus. Paul cared about Felix and his wife; he wanted them to accept Christ and be saved.

Ellicott's Commentary for English Readers
Drusilla. She was, according to Josephus, the daughter of Herod Agrippa I., who "killed James with the sword" and died shortly afterwards. She was first the wife of Azizus, King of Emesa; but Felix, becoming enamored of her on account of her singular beauty, employed a certain magician, a Jew named Simon, to entice her away from her husband, and persuade her to marry him, contrary, as Josephus says, to the institutions of her country. She perished, with Agrippa, her only son by Felix, in the eruption of Vesuvius, in the reign of Titus

"But as he was discussing righteousness, self-control and the judgment to come, Felix became frightened and said, "Go away for the present, and when I find time I will summon you."

Paul spoke of righteousness, which meant he was explaining the way a good person would live out his life in Jesus. 
He spoke of self-control, which it seems from Felix's past, was not one his attributes. 
He spoke of the judgement to come, when all people will be judged by the works they have done. 

All this frightened Felix. He obviously felt himself to be far from righteous and was worried that he may one day be judged by God.

MacLaren's Expositions
Felix and his brother had been favorite slaves of the Emperor, and so had won great power at court. At the date of this incident he had been for some five or six years the procurator of the Roman province of Judaea; and how he used his power the historian Tacitus tells us in one of his bitter sentences, in which he says, ‘He wielded his kingly authority with the spirit of a slave, in all cruelty and lust.’

Jamieson-Fausset-Brown Bible Commentary
Felix trembled—and no wonder. For, on the testimony of Tacitus, the Roman Annalist [Annals, 9; 12.54], he ruled with a mixture of cruelty, lust, and servility, and relying on the influence of his brother Pallas at court, he thought himself at liberty to commit every sort of crime with impunity. 

We do not know if Felix and his wife ever gave their lives to God; we only know what Felix said to Paul, that he didn't want to think about these things now, maybe later.

It isn't safe to put off our salvation. We are human, we could die at any moment. Also, after putting God off for months and years, we may become so dead to what is right that we may never hear his voice in our hearts again. This is what Jesus meant when he said, ""Therefore I say to you, any sin and blasphemy shall be forgiven people, but blasphemy against the Spirit shall not be forgiven."  Matthew 12:31

If we continually turn away from the Spirit of God then nothing can save us.

Hatred of God.

"If I had not come and spoken to them, they would not have sin, but now they have no excuse for their sin." John 15:22

Ellicott's Commentary for English Readers

If I had not come and spoken unto them, they had not had sin.—In this and the following verses our Lord shows the sinfulness of the world’s hatred, because it was in the face of His revelation to them by both word and work . Apart from this revelation, their sin would have belonged to the times of ignorance, which God overlooked (Acts 17:30-31). It would have been the negative evil of men who know not. It was now the positive evil of men who, knowing the truth, willfully reject it.


"If I had not done among them the works which no one else did, they would not have sin; but now they have both seen and hated Me and My Father as well." John 15:24

Pulpit Commentary
Verse 24. - If I had not done among them works which none other did Here he comes down from "Word" to "work," and indicates the lower agency, that of works, which are neither inoperative nor valueless, and which transcend all other similar deeds. They are works of the Son of God, works of creation and of healing, triumphant conflict with the forces of nature and the malice of the devil, of a kind which may be compared with, but which exceed all human and angelic ministry. They had not had sin, but now they have both seen and hated both me and my Father. The works as well as the words of Christ might have softened their hearts, but the Divine claims, which were thus pressed home upon the conscience, provoked their malice. "They took counsel to kill him;" "They took up stones to stone him." They hated God as God, and goodness and truth just because they were goodness and truth. The awful condemnation is here pronounced, "that men loved darkness rather than light." They positively saw their Father, and hated him. This is the most terrible condemnation that can be pronounced on moral beings.
