What does the Bible say about being witnesses of Christ?

The Scriptures declare that God makes His people witnesses of His grace. In Isaiah 51, God urges His people to 'awake' and recognize their transformed status as witnesses of salvation in Jesus Christ. This call emphasizes the importance of sharing the gospel, as believers not only accept God's grace but are also tasked with actively proclaiming it. In Acts 26, the Apostle Paul describes his calling to be a minister and a witness, highlighting that witnessing is an integral part of the Christian life defined by the power of the Holy Spirit working within us.
