O death, where is thy sting? O grave, where is thy victory? The sting of death is sin; and the strength of sin is the law. But thanks be to God, which giveth us the victory through our Lord Jesus Christ. Therefore, my beloved brethren, be ye stedfast, unmoveable, always abounding in the work of the Lord, forasmuch as ye know that your labour is not in vain in the Lord. -1 Corinthians 15:55-58

For the LORD your God is he that goeth with you, to fight for you against your enemies, to save you. -Deuteronomy 20-4
