2 Ch 20:4.
King Jehosaphat was faced with a situation that seemed insurmountable. Those who were against him were much more than those on his side based on what he could see. But Jehosaphat knew something. He knew that if he went to God, he would know what to do in order to emerge victorious from this situation. Jehosaphat received instructions from God on what to do, and he obeyed God's instructions. And the Bible records that God fought the battle on his behalf. Jehosaphat won the battle because God showed up in His situation.
God wants to win our battles for us. But we must acknowledge Him, and seek His instructions. And as we follow His instructions, we will enjoy sweatless victories.
