Therefore, my beloved brothers, be steadfast and immovable. Always excel in the work of the Lord, because you know that your labor in the Lord is not in vain. — 1 Corinthians 15:58

"be steadfast and immovable. Always excel in the work of the Lord". Paul closes the resurrection chapter with marching orders. Walk in Christ, rooted and built up in him. We work with Christ for your joy, for you stand firm in the faith. Don't grow weary — your labor in the Lord is not in vain.
