1 Corinthians 15:56-58

Amplified Bible

⁵⁶ The sting of death is sin, and the power of sin [by which it brings death] is the law; ⁵⁷ but thanks be to God, who gives us the victory [as conquerors] through our Lord Jesus Christ.

⁵⁸ Therefore, my beloved brothers and sisters, be steadfast, immovable, always excelling in the work of the Lord [always doing your best and doing more than is needed], being continually aware that your labor [even to the point of exhaustion] in the Lord is not futile nor wasted [it is never without purpose].
