So, then, brothers and sisters, don’t let anyone move you off the foundation of your faith. Always excel in the work you do for the Lord. You know that the hard work you do for the Lord is not pointless. (1 Corinthians 15:58 GWT)
Be on your guard; stand firm in the faith; be men (people) of courage; be strong. Do everything in love. If anyone does not love the Lord–a curse be on him. Come, O Lord! [the Lord is coming!] (1 Corinthians 16:13, 14, 22 NIV84)
Standing firm, being faithful and doing what God sets before us to do. These things are not glorious in themselves, but they are needed, powerful, and too often lacking.
