What do witnesses teach about testimony?
What does "witnesses of all He did" teach about Christian testimony?

The Setting: Acts 10:39

“We are witnesses of all that He did, both in the land of the Jews and in Jerusalem. They also put Him to death by hanging Him on a tree.”

Peter is speaking in the household of Cornelius, recounting Jesus’ ministry, death, and resurrection. His phrase “witnesses of all that He did” becomes a template for every believer’s testimony.


Witnesses of What? The Content of Testimony

• Not merely opinions or feelings

• Not a selective highlight reel

• The totality of Jesus’ words, works, death, and resurrection (cf. Acts 1:3; Acts 1:22)

Our testimony carries weight because it is anchored in historical, objective acts of God.


Witnesses of All He Did: Scope and Completeness

• “All” signals a comprehensive message—miracles, teaching, compassion, confrontation, cross, and empty tomb.

• It guards us from trimming uncomfortable truths (John 6:60–68).

• It calls us to a balanced gospel: grace and truth, love and lordship (John 1:14).


Witnesses of All He Did: Personal Experience

• Peter speaks as an eye- and ear-witness (1 John 1:1–3).

• While modern believers were not there physically, we bear witness to Jesus’ transforming work in our own lives (2 Corinthians 5:17).

• Personal encounter plus Scriptural certainty produces compelling testimony (Acts 4:20).


Witnesses of All He Did: Public Proclamation

• The disciples took their witness beyond private circles to the broader world (Luke 24:47-48).

• Christian testimony is meant for both “the land of the Jews and Jerusalem” and to “the remotest part of the earth” (Acts 1:8).

• Our audience includes neighbors, coworkers, and the nations.


Witnesses of All He Did: Empowered by the Spirit

• Jesus promised power for witness (Acts 1:8).

• The Holy Spirit turns observers into bold proclaimers (Acts 4:31).

• Authentic testimony is Spirit-enabled, not self-generated (1 Corinthians 2:4-5).


Living It Out Today

• Know the whole story—immerse yourself in the Gospels and Acts.

• Tell the whole story—include Jesus’ life, death, resurrection, and personal implications.

• Live the whole story—demonstrate transformed conduct that matches the message (Philippians 2:15-16).

How can we be effective witnesses like those in Acts 10:39 today?
