How do we know God's intervention is necessary for salvation?

The necessity of God's intervention for salvation is underscored in passages such as Ephesians 2:1, which states that we were dead in our trespasses and sins. Without being made alive by God's grace, individuals cannot even recognize their need for salvation or come to Christ. The sermon illustrates how only by the sovereign work of the Holy Spirit can a person be awakened to their sinful state and be enabled to seek God. This aligns with the historic Reformed understanding that salvation is entirely a work of God’s grace, independent of human will.
