“While Peter yet spake these words, the Holy Ghost fell on all them which heard the word.” — Acts‬ ‭10:44‬ ‭KJV‬‬

One of the most essential and encouraging truths in all Scripture about preaching the gospel is that the Spirit of God works mightily while we preach.

The Spirit of God punches His timecard when you proclaim the full gospel to the lost. The Spirit engages in CPR, reviving a heart once dead when you engage in evangelism (Eph. 2:1). He shines gospel light in darkened hearts when the blazing gospel torch is carried to those in darkness (2 Cor. 4:6). The Spirit opens blinded eyes when you call the unregenerate to look away from themselves to Christ (2 Cor. 4:4).

The very first thing He does is convict, according to Jesus. He said, “And when he comes, he will convict the world concerning sin and righteousness and judgment” (John 16:8). The Spirit puts a person’s conscience on trial when the gospel is published. And He says to them, “You are in serious trouble with God, and you are in serious need of salvation. Wake up! God is holy and you are not. You need Jesus!”

Furthermore, the Spirit converts a sinner’s soul. Paul said:

“But when the goodness and loving kindness of God our Savior appeared, he saved us, not because of works done by us in righteousness, but according to his own mercy, by the washing of regeneration and renewal of the Holy Spirit, whom he poured out on us richly through Jesus Christ our Savior” (Titus 3:4-6).

He regenerates the unregenerate soul. He creates new life within a person devoid of spiritual life.

The Spirit does it all, and oftentimes in the very moment we present the gospel.

This does not mean that every person who hears the gospel will be saved. Sometimes your gospel preaching falls on deaf ears. Unsaved sinners still resist grace (cf. Acts 7:51).

What it does mean is that Spirit can penetrate the hardest heart, loosen the stiffest neck, and overcome anyone’s resistance to His call when He wills (John 6:37-40; Acts 16:4; Romans 8:29-30).

What it does mean is that you can faithfully present the gospel and walk away with a full heart, knowing that the Spirit leads a person to Christ.

What it does mean is that you don’t have to worry about whether your presentation of the gospel was eloquent or sophisticated enough to convince someone to believe.

What it means is that you don’t have to use gimmicks, tactics, bouncy-houses, potlucks, or concerts to win a person to Christ.

And it means that no amount of therapy, theories, or prescriptions make a person a better candidate for salvation.

The Spirit of God alone convicts and converts lost souls—and He doesn’t need any help. Just preach the gospel (Romans 10:14-17).
