Ephesians 4:17-19

This I say therefore, and testify in the Lord, that you no longer walk as the rest of the Gentiles also walk, in the futility of their mind, being darkened in their understanding, alienated from the life of God, because of the ignorance that is in them, because of the hardening of their hearts; who having become callous gave themselves up to lust, to work all uncleanness with greediness.

SERMON DESCRIPTION The greatest hindrance to belief in the gospel does not arise from human intellect, but from the heart that has been darkened by sin. In this sermon on Ephesians 4:17–19 titled “Darkness and Light,” Dr. Martyn Lloyd-Jones highlights the warning of Christ that all people in their natural state are alienated from God and unable to pursue what is good and right. This is because the effects of the fall extend to every aspect of humanity. It corrupts the mind, hardens the heart, and distorts the will. Despite this fallen state, humanity still places great worth and confidence in their ability to reason and know morality. This is evident in the many great philosophers of the ancient world who after all their learning and knowledge were still never able to come to true knowledge of God. As Dr. Lloyd-Jones teaches, this shows that what people need is not simply more knowledge, but a new heart and mind that is freed from the mastery of sin and its domination. However, freedom from sin comes only through the gospel of grace and the sovereign working of the Holy Spirit. This is why it is so important to pray that God would work in the hearts and minds of others to reveal Himself to them and give them a true understanding of the gospel of Jesus Christ.

SERMON BREAKDOWN

1. The apostle Paul describes the vain and empty life of unbelievers in Ephesians 4:17-19.
2. Their lives are aimless and pointless, amounting to nothing in the end.
3. Paul explains why people live this way. He says their understandings are darkened and they are alienated from the life of God due to ignorance and hardness of heart (Ephesians 4:18).
4. The most disastrous effect of the Fall was the darkening of human understanding. The Bible frequently refers to unbelievers as "fools" who lack understanding.
5. Unbelievers live in darkness and cannot see the truth, even though they claim to be wise (1 Corinthians 1-2).
6. The gospel is compared to light overcoming darkness. When people are saved, their eyes are opened and they are turned from darkness to light (Acts 26:18).
7. Even the most intelligent unbelievers have darkened understanding. Their intellects are useless until enlightened by the Holy Spirit.
8. Christians should not be surprised or troubled that unbelievers reject the gospel. Their understanding is darkened so they cannot see the truth.
9. Christians' duty is to pray for revival - for the Holy Spirit to open blind eyes and overcome darkness. No human effort can overcome spiritual darkness. Only the Spirit can do this.
