“Come and hear, all who fear God, And I will tell of what He has done for my soul” Psalm 66:16 (NASB). Our propositional presentations of the gospel cannot compare with a clear witness of what God has done in our lives.  The former is canned, and the latter is a true witness.  If we know what God has done for us, and we have experienced His grace, then we have a story to tell.  It does not have to be dynamic nor dramatic.  A simple story that verbalizes our gratitude to our Lord is a powerful thing.
