Say it until your heart sings with the Joy of the safety and power it means to you.
Say it until the very force of the utterance drives back, and puts to naught, all the evils against you.
Use it as a battle cry - "All power is given unto My Lord," "All power is given unto My Friend," "All power is given unto My Savior," and then you pass on to victory.
"He ruleth by his power for ever." - Psalm 66:7
