Joan Boney ... apostle/prophet
When Paul was at Jerusalem, he was brought before the people and he explained what had happened to him on the road to Damascus (Acts 9), how he was setting about to find and imprison those who were of Jesus when a light shined around him and Jesus spoke to him ...
Ananias was sent to Paul by God to open his eyes and Ananias said to Paul:
The God of our fathers hath chosen thee, that thou shouldest know his will, and see that Just One, and shouldest hear the voice of his mouth. 15 For thou shalt be his witness unto all men of what thou hast seen and heard. 16 And now why tarriest thou? arise, and be baptized, and wash away thy sins, calling on the name of the Lord. Acts 22
This is exactly what each of us who have heard from God do ... We tell others that which God has said to us and has done with us ... this makes us HIS witness ... (We do not try to witness. We are a witness.)
Paul had one story of what God did in his life. I have another story of what God has done in my life. You have another story of what God has done in your life. Each time we share that story, we are HIS witness.
