Answer:
Witnessing comes from the idea of giving a testimony—sharing what you have personally seen or experienced. For example, if someone witnesses a car accident and then tells others exactly what happened, they are giving a testimony or bearing witness to that event.
In Christian, witnessing (or bearing witness) is sharing firsthand experience of Jesus Christ—His character, His works, and His impact in one’s life. This is a vital part of the Great Commission (Matthew 28:19-20), where Jesus commands His followers to “go and make disciples.” Sharing your testimony about Jesus’ love and power is a powerful way to introduce others to Him.
Preaching, however, is a broader ministry that includes witnessing but also involves teaching, exhorting, warning, and explaining God’s Word. It is a more comprehensive proclamation of the Gospel message.
For instance, if the person who saw the car accident not only describes what happened but also teaches how to prevent such accidents and warns others about the dangers, they are preaching. In the same way, when a Christian moves from simply sharing personal experiences about Jesus to explaining the significance of His death and resurrection, calling people to respond in faith and repentance, they are preaching.
Preaching involves not just telling what Jesus has done but also calling for a response, emphasizing salvation, repentance, and obedience (2 Timothy 4:2,
“Preach the word; be prepared in season and out of season; correct, rebuke and encourage—with great patience and careful instruction.”).
As believers, we are called both to witness—to share personal testimonies—and to preach, to proclaim the full Gospel message.
2 Timothy 4:5 reminds us:
“But you, keep your head in all situations, endure hardship, do the work of an evangelist, discharge all the duties of your ministry.”
