A very powerful combination is found in Revelations 12:11. The blood of Christ (the Lamb) that was sacrificed for our redemption and the word of our testimony. They are an unstoppable force, that has the power to change hearts, to restore lives, to deliver and to save.
This is how we overcome and destroy the plans of the enemy is peoples lives.
The blood that was shed for us remains un-silent from then until now, and throughout all eternity. We must never allow our voice to be silenced, for our testimony is a witness of the truth, promises and faithfulness of our Heavenly Father.
