The 15-second testimony is designed for people on the go who may not have time to listen for long. However, think of this short format as the framework of your full testimony. There will be times when people are more interested and willing to hear more details, giving you more time. You can build on the 15-second testimony by adding more details as the listener allows. Practice telling your testimony in various lengths: 15 seconds, 30 seconds, 1 minute, 3 minutes, 5 minutes, and even longer. Be prepared for any scenario, as those who want more depth will appreciate it. Regularly reflect on and practice sharing your testimony in different time frames. Below are resources to help you delve deeper into your testimony.
