'Inflexibility' in the Bible

Turn to me, and be gracious to me;Grant Your strength [Your might and the power to resist temptation] to Your servant,And save the son of Your handmaid.

Seek and deeply long for the Lord and His strength [His power, His might];Seek and deeply long for His face and His presence continually.

On the day I called, You answered me;And You made me bold and confident with [renewed] strength in my life.
