What was the mystery kept secret in the mind of God that Paul revealed?
The mystery was that God would take salvation to the Gentiles by faith alone, without Israel, even though Israel rejected Him and was dispersed among the nations. This secret, kept in God’s mind since the ages began, is now revealed through the gospel of grace.
Les explains that the mystery was a total secret kept in the mind of God: God would take salvation to the Gentiles without Israel, even though Israel rejected Him and was displaced from Jerusalem and dispersed into the nations. Now He has gone to the Gentiles with the Gospel of the grace of God. The word “mystery” is the same Greek word meaning secret. Romans 16:25 speaks of the revelation of the secret kept secret since the age began; the word “world” there is aion in Greek, meaning the age of the ages. Ever since the creation of man, it had never been revealed that God would take salvation to the Gentiles by faith, and faith alone. All the Old Testament was by way of Israel. I Corinthians 2:7 also deals with wisdom.
