Nothing has the life-transforming power of the word of God. It alone can transform a life. God personally stands as a guarantor of everything written in the Bible. But God has another instrument that wields great influence for His kingdom as well. That is your testimony. When you convey to others, in your own words, what God has done in your life, the Holy Spirit can accomplish much. While your words might not be eloquent, and your theological understanding might be limited, no one can refute your experience. People might argue with your conclusions, but it is difficult to negate your experience.
That is why we must share what God has done in our life with as many people as possible. The woman at the well had little credibility with the townspeople where she lived. Yet everyone who saw her could tell that she had undergone a life-changing experience. Even those who have been shunned by society can offer their testimony in service to Christ.
When the woman recalled for others what Jesus had done in her life, an entire village turned to Christ. She preached no sermon. She taught no lessons. She simply told others what Jesus had done for her. That was enough. Revival came. Is there someone with whom you could share your testimony today?
