As God -Jesus- declares us His witnesses, we need to learn of Him, to see just what are our obligations, responsibilities, and duties are as a witness. The word of God has to be obeyed unless we find ourselves hostile witnesses. Jesus commissioned us to go into all the world, Paul says we should do the work of an Evangelist. As bond-servants of Christ, we must not be slothful, non be guilty of having someone's blood on our hands.
