Acts 3:15, "And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses."
The early disciples who became the apostles of Jesus were all witness of his life, ministry, death, burial, and resurrection. They knew these facts to be true because they saw it with their eyes and heard it with their ears. They touched him with their hands.
They heard him, they saw him, they looked upon him, and their hands handled him. 1 John 1:1.
Lord, I am a witness because of how you healed me, saved me, delivered me, and changed my life. I am a witness to the power of God through the name of Jesus Christ. Lord, you cast the devil out of me. You delivered me from the devil. You saved me out of deep darkness, and you brought me into the kingdom of Jesus Christ. I was forever changed when you filled me with the Holy Spirit in 1989. I was never the same again. I went from death to life. I am a witness of you, Lord. I am a witness for you. Forever and always. Amen.
