Isaiah 53-55, Psalm 128, 1 Corinthians 15
My wife suggested that if I lose a little weight, I would snore less. So I exercised. I kept eating ice cream and cookies. My exercise was in vain.
I wanted to be a millionaire, so I set out to make a lot of money. Then I bought cars and houses and boats and stuff. My work was in vain.
I wanted a college education, so I went to college. I partied and played. I got my degree, but the education was in vain.
I heard the Good News. I stand in it. Through it, I am saved. Unless, I believed in vain (1 Cor 15:1-2).
If I believed in vain, then Jesus gave me great grace in vain (1 cor 15:10).
