“You are my witnesses…so that you may know and believe me and understand that I am he.” (Is 43.10).  

Jesus tapped into this passage from Isaiah when he told his followers to be his witness (Acts 1.8) and when he commanded them to teach everyone to obey all he instructed (Mt 28.18-20).  Teaching others to obey includes sharing his goodness and demonstrating his love in such a way their eyes and ears will be opened to see and hear the goodness of God.  But, on a personal level, we will increase in our own belief, learning and understanding of who He is as we declare and demonstrate the nature of God.

Jesus lived as a witness to the heart, character and nature of the Father.  His life was a perfect representation of God (Hb 1.3).  He also said that anyone who looked at him, would see the Father (Jn 14.9).  This is the life we are called to replicate; to live as witnesses of God; to become witnesses of God.

The Hebrew word for witness contains an element of testimony or giving evidence within the definition.  The New Testament Greek word for witness also contains a legal, evidence-based meaning.  So, to be a witness, means to tell the story, to give testimony to the nature and acts of God.  As we testify, we give evidence of his character so others may believe and understand He is God.  In the process, we reaffirm and deepen our own belief – which increases our understanding – and helps us to become more like him.

There are a lot of ways the Church has embarked on this task of witnessing about God.  But, rather than attempting a programme or strategy, being a witness of God is more authentic when we know WHO we believe.  When we know Him, our testimony is an overflow of his love, mercy, goodness and kindness we’ve experienced.  Simply talking about WHAT we believe does not carry the same life-giving power.

Our role as witnesses of God is to represent Him; to reflect Him.  We can only accurately reflect him to the extent we are being transformed into His likeness (1 Cor 3.18).  Therefore, our purpose is to become transformed into His image so He lives through us (Gal 4.19).  At all times being sensitive to Holy Spirit who leads and empowers us for service until we are filled with the whole measure of the fulness of God (Eph 4.13) and, together, display the manifold wisdom of God (Eph 3.10).  Then, as witnesses who prove the wisdom of God (cf Lk 7.35) those who ‘see and hear’ will recognise the life of God through us, respond to it by applying faith and come to believe that He is God.

In the process, we increase in our understanding of WHO He is.
