1 Chronicles 12:16-18 (KJV)
16 And there came of the children of Benjamin and Judah to the hold unto David.
17 And David went out to meet them, and answered and said unto them, If ye be come peaceably unto me to help me, mine heart shall be knit unto you: but if ye be come to betray me to mine enemies, seeing there is no wrong in mine hands, the God of our fathers look thereon, and rebuke it.
18 Then the spirit came upon Amasai, who was chief of the captains, and he said, Thine are we, David, and on thy side, thou son of Jesse: peace, peace be unto thee, and peace be to thine helpers; for thy God helpeth thee. Then David received them, and made them captains of the band.

People Can See God In Us
Nobody can come against God and win the battle. The same can be said for people that rely upon God, for He is their fortress in times of need.
