The last thing that Jesus told His disciples before ascending up into heaven was, " and you will be my witnesses "! You will find this in Acts 1:8, and notice that this is a mandate for believers and will be accompanied by an endowment of power from on high to accomplish what we have been instructed to do. Simon J. Kistemaker in his commentary on Acts (page 54) identifies witness as twofold. First, it refers to the person who has observed an act or event. Next, it refers to the person who presents a testimony by which he defends and promotes a cause. The act which we have observed is the transformation of our lives or that of someone else when converted by grace to a saving faith in Jesus Christ. As we testify to this fact with others we are acting as a witness of what God has done. We do not have the ability to convert/transform such a person but only to plant a seed of faith that we believe the Holy Spirit will bring to life in due time by His power. Some have asked me exactly what is it that we share in our witness? This is a very good question which has many answers. The Holy Spirit may lead you to any number of passages that are helpful. Here is one that is found in I Corinthians 15: 3-5, "For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that He was raised on the third day according to the Scriptures, that He was buried, that He was raised on the third day according to the Scriptures, and that He appeared to Peter, and then to the Twelve." Of course there are many more passages that I could have quoted but this one really is the brief summation of the Gospel. Could you share this with another? Why not? Remember that a witness is like someone once said, "One beggar telling another beggar where to find bread." Jesus is that Bread of Life and our witness in the life is to point others to Him. Let me know how you are doing in this most important task of the committed disciple.
