1 Corinthians 15:55-58

55O death, where is thy sting? O grave, where is thy victory? 56The sting of death is sin; and the strength of sin is the law. 57But thanks be to God, which giveth us the victory through our Lord Jesus Christ.

58Therefore, 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.
