Our role as Christians to preach?
What does "He commanded us to preach" reveal about our role as Christians?

The command in context

“ ‘And He commanded us to preach to the people and to testify that He is the One appointed by God to judge the living and the dead.’ ” (Acts 10:42)

Peter is explaining to Cornelius that sharing the gospel is not a suggestion; it is a direct order from the risen Christ.


A universal assignment, not a selective call

• Jesus issued this mandate to the apostles, yet their letters show the baton passes to every believer (2 Timothy 4:2; 1 Peter 3:15).

• The Great Commission echoes the same rhythm: “Go therefore and make disciples of all nations” (Matthew 28:19).

• Our role: every Christian is a messenger, regardless of age, background, or gifting.


Preaching as telling—everyday language

• The Greek term kēryssō means “to herald, announce, proclaim.”

• It is less about a pulpit and more about clear, public declaration—coffee shops, living rooms, office hallways.

• Ordinary speech can carry extraordinary truth when centered on Christ.


Testifying: words backed by witness

• “To testify” (martyréō) adds weight: we share what we know firsthand.

• Our changed life validates our spoken message (Acts 1:8).

• Credibility grows when listeners see consistency between gospel words and gospel fruit.


The message we carry

• Jesus is God-appointed Judge—so people need salvation (John 5:22–24).

• Jesus is living Savior—so salvation is available (Acts 4:12).

• The cross, resurrection, and call to repentance form the non-negotiable core (1 Corinthians 15:3-4).


Powered by the Spirit

• The same Spirit who fell on Cornelius’ household (Acts 10:44) empowers our witness.

• Boldness comes from dependence, not personality (Ephesians 6:19).

• Prayerful reliance keeps preaching relational, not mechanical.


Practical ways to obey today

• Share a concise testimony: who Jesus is to you, in three minutes.

• Open Scripture with a friend; let them read a gospel paragraph aloud.

• Use everyday platforms—texts, social media captions—to drop seeds of truth.

• Support missions, church plants, and evangelistic outreaches financially and with hands-on help.

• Integrate gospel statements into normal conversations: “That reminds me of how Jesus…”


Encouragement from other passages

Mark 16:15 — “Go into all the world and preach the gospel to every creature.”

Romans 10:14-15 — People cannot believe unless someone tells them.

2 Corinthians 5:20 — “We are therefore ambassadors for Christ.”

The phrase “He commanded us to preach” settles the question of our purpose: we are appointed spokespeople, Spirit-enabled, carrying the most urgent news humanity will ever hear.
