Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect” 1 Peter 3:15 NIV.
Each believer has a unique story that can minister to others. We call it testimony.
We can be more prepared to share that story if we practice in front of our peers. I used to give testimony to my peers before I visited churches or went on retreats. Each time I spoke it became easier. Often I would write out what to say. Praying before saying is vital. Asking others to pray is also very important. Make sure your doctrine is based on sound Bible teaching. You may use a quote or current vernacular but it should not conflict with Scripture.
Our Sunday Children's Sermon talked about words like blowing on a dandelion*. Whether positive or negative our words go forth like those seeds and plant themselves in far-reaching places. I remember learning the saying from Carl Sandburg: "Look out how you use proud words." Season your story with humility and compassion.
