When someone is summoned to court as a witness, that person is there to testify to what he or she has seen or heard related to a particular case.
Witnesses are called forward to share their personal knowledge and swear to tell the whole truth and nothing but the truth as he or she personally knows it. Witnesses are not called to tell what they may have heard from someone else. Judges disqualify such secondhand testimony, and juries are instructed to disregard such as hearsay.
In Sunday’s First Reading for The Ascension of the Lord (Acts 1:1-11), we learn that the Risen Lord summoned his apostles to be his witnesses. He told them, “You will receive power when the Holy Spirit comes upon you, and you will be my witnesses in Jerusalem, throughout Judea and Samaria, and to the ends of the earth.”
The Lord Jesus instructed his apostles to testify to what they had personally heard him say and do. They were to tell others about the sermons they heard him preach. They were to report how they saw him heal the sick, open the eyes of the blind, free the possessed, feed thousands with a few loaves and fish, raise the dead, confront sin and evil, and expose religious hypocrisy. They were to relate the story of his passion, death, and resurrection. They were to tell of their meetings with him after he came forth from the tomb. They were to share how they came to know that Jesus their teacher was their Savior, Messiah, Lord, and God!
Throughout the Acts of the Apostles, we learn how these disciples powerfully testified to what they had heard and seen. Their testimony brought thousands of people to faith in Christ and their message spread far beyond the city of Jerusalem, even to Rome itself.
Today, as we hear in Sunday’s Gospel (Matthew 28:16-20), we are to continue the work of the first disciples and “make disciples of all nations.” We are to share the Good News of the Gospel and to testify that Jesus is the Way, the Truth, and the Life.
We must do more than just tell others what other people have told us about Jesus and offer more than just hearsay testimony. We cannot be witnesses who only speak about what we have read about him in the Scriptures or learned about him in programs of religious instruction.
We need to be witnesses who can testify to our personal knowledge of Jesus Christ. We have to be able to speak about our relationship with him. We have to testify to what the Lord Jesus has done in our lives and what we have seen him do in the lives of others.
May the Holy Spirit, who empowered the first disciples to be powerful witnesses for Jesus, inspire us to be effective witnesses who can personally testify on behalf of Jesus Christ!
