WITNESS
Definition:
The Christian Meaning of “Witness”
In Christianity, witness refers to both:
A person who testifies to what God has done — especially through Jesus Christ
An action — the act of declaring, showing, or living out the truth of the gospel
A witness is someone who sees, knows, and tells the truth about God.
It is both an identity and a mission, rooted in Scripture and empowered by the Holy Spirit.
BIBLICAL FOUNDATIONS

“You are My witnesses,” declares the LORD. — Isaiah 43:10
“You are My witnesses… Is there a God besides Me?” — Isaiah 44:8

This truth shows that witness is not a New Testament invention — it is God’s ancient calling.
You can see your witness as part of God’s long story of revealing Himself to the world.
B. New Testament Fulfilment in Christ
“You will be My witnesses… to the ends of the earth.” — Acts 1:8
John testifies to what he has “seen… heard… and touched.” — 1 John 1:1–3
“You also will bear witness, because you have been with Me.” — John 15:27
Being with Christ naturally leads to witness
