Sometimes, you have to encourage yourself!
On a certain occasion in the Old Testament, David and his men returned to their camp. When they returned, they discovered that the enemy had invaded the city and captured their wives, sons, and daughters. After David and his men had a pity party, David realized that his own men planned to kill him and David encouraged himself.
It was only when David encouraged himself that he had a conversation with God. God gave him permission to go into the enemy's camp and take back everything that the enemy had stolen.
There are times, in life, when we have to encourage ourselves. When others turn their back on you, encourage yourself! When it seems as if the whole world is against you, encourage yourself!
but David encouraged himself in the LORD his God.
(I Samuel 30:6)
