The Difference 4.4.21
So, my dear brothers and sisters, be strong and immovable. Always work enthusiastically for the Lord, for you know that nothing you do for the Lord is ever useless.
(1 Corinthians 15:58).
Lots of faiths have sacred teachings. The authors of those teachings are revered. However, only One proved they were who they said they were by rising from the dead and ascending to Heaven several weeks later. His name is Jesus!
This is the reason we can be strong and immovable. We know that nothing we do for the Lord is ever useless because we are following the man who rose from the dead! It doesn't matter what names others call us . . . because of His resurrection, I trust Him with my life and my eternity.
