A testimony is meant to express how and why one lives according to God. It honors God, reminds us of his goodness, and encourages others. An effective testimony is built upon what Christ has done for us and continues to focus on Jesus. It is important for believers to understand key truths about God's love, man's sinfulness, Christ's payment for sin, salvation as a gift, and having eternal life through receiving Jesus. One's testimony should be updated daily to reflect their current understanding of what God has revealed.
