You will not need to fight in this battle. Position yourselves, stand still and see the salvation of the Lord , who is with you, O Judah and Jerusalem!’ Do not fear or be dismayed; tomorrow go out against them, for the Lord is with you.”
II Chronicles 20:17 NKJV
Are you trusting the Lord to battle for you? To give you the strength to win? Sometimes God told Israel they would have to prepare for the fight and actually fight. Other times, they prepared but God took care of the enemy for them and all they had to do was collect the spoil.
