Acts 1:8 WITNESSES UNTO ME The personal testimony of the real witness [Acts 1:1-8] makes what they have to say of great value. What a person has learned by experience can't be denied. No one can take from a person that which has actually happened to them. The only consideration when passing on a personal witness to others is that it must be scriptural to be right. If what a person testifies about is based on feelings, dreams or opinions that are condemned or contrary to the Bible teaching, it is not given by the Holy Spirit. A person with talent, training, and experience but without spiritual power is ineffective. Personal experience must be behind all true teaching and preaching. "After that the Holy Ghost is come upon you..."
The power of the real witness [Acts 1:8] is very impacting to those who watch as well as hear what he/she has to say. Empowerment from the Holy Spirit is not limited to strength beyond the ordinary. It involves courage, boldness, confidence, insight, ability and authority. We are animated and given power by a better spirit than our own. This enables us to preach the Gospel and prove it from the scriptures. These did not have strength of their own for preaching, nor wisdom, nor courage enough. But Christ's witnesses receive Christ's power for the work to which He calls them. He will qualify those He uses in His service and be with them in that service. They would proclaim Him King; and publish those truths to the world how His kingdom will be set up and how He would rule. They would prove this message with the proof of the gifts and the confirmation of their own testimony and experience in Jerusalem, Judea, Samaria and the uttermost parts of the earth. They would witness with extraordinary results.
The progress of the real witness [Acts 1:8] guides as to the time, place and the manner of testimony we should give. They were to wait for the Spirit to be sent. They were to be in a position and condition to receive the Spirit and He would give them power. He would produce amazing results through them. The disciples had seen and heard the Lord Jesus Christ after His resurrection but needed divine power to declare what they had seen.
