Testimony is an articulating story of how God has helped you to lead a more sanctified life. This may include how you became a Christian, why you attend church where as before you didnít or how you received a blessing or a healing.
The reason of giving a testimony is either to glorify Christ or giving thanks to His wonders. As the bible says from 1st Peter 3:15;
As a Christian you ought to pray for the Holy Spirit to guide you in your presentation and your speech to be short and take not more than 5minutes."Always be prepared to give an answer to everyone who asks you to give a reason for the hope that you have."
Name the Savior in the course of the testimony and tell about the changes in your life as a result of becoming a Christian.
