1 Corinthians 15:56-58

56 and the sting of the death [is] the sin, and the power of the sin the law;

57 and to God — thanks, to Him who is giving us the victory through our Lord Jesus Christ;

58 so that, my brethren beloved, become ye stedfast, unmovable, abounding in the work of the Lord at all times, knowing that your labour is not vain in the Lord.
