58 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.
English Standard Version
58 Therefore, my beloved brothers, be steadfast, immovable, always abounding in the work of the Lord, knowing that in the Lord your labor is not in vain.
58 With all this going for us, my dear, dear friends, stand your ground. And don't hold back. Throw yourselves into the work of the Master, confident that nothing you do for him is a waste of time or effort.
