Not only does the power of the Spirit produce life and victory in Christ, He also empowers the believer to be a witness of Christ in lifestyle and testimony.
And look, I am sending you what My Father promised. As for you, stay in the city until you are empowered from on high (Luke 24:49).
But you will receive power when the Holy Spirit has come upon you, and you will be My witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth (Acts 1:8).
Certainly, this promise and fulfillment applied to Christ’s disciples. Nevertheless, every believer is clothed with power from on High at regeneration and should be a witness of life in Christ, testifying to his personal experience with Christ.
But set apart the Messiah as Lord in your hearts, and always be ready to give a defense to anyone who asks you for a reason for the hope that is in you (1 Peter 3:15).
Should Christians expect help from the Holy Spirit to witness in times of persecution?
But when they hand you over, don’t worry about how or what you should speak. For you will be given what to say at that hour, because you are not speaking, but the Spirit of your Father is speaking through you (Matthew 10:20).
If this promise made to the Twelve is applicable to all Christians, we can expect the Holy Spirit to give us words to speak when persecuted for His Name’s sake.
