Those who wait on the Lord shall renew their strength. 

When I am weak, then I am strong. § My God shall be My strength. § He said to me, “My grace is sufficient for you, for My strength is made perfect in weakness.” Therefore most gladly I will rather boast in my infirmities, that the power of Christ may rest upon me. § Let him take hold of My strength.Cast your burden on the Lord, and He shall sustain you. § The arms of his hands were made strong by the hands of the Mighty God of Jacob.I will not let You go unless You bless me!You come to me with a sword, with a spear, and with a javelin. But I come to you in the name of the Lord of hosts, the God of the armies of Israel, whom you have defied. § Plead my cause, O Lord, with those who strive with me; fight against those who fight against me. Take hold of shield and buckler, and stand up for my help.
