1 John 5:10-12
Whoever believes in the Son of God has the testimony in himself. Whoever does not believe God has made him a liar, because he has not believed in the testimony that God has borne concerning his Son. And this is the testimony, that God gave us eternal life, and this life is in his Son. Whoever has the Son has life; whoever does not have the Son of God does not have life.
-the story of redemption brings life
And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death.
-people need to know your testimony so they may overcome
