"One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind" (Rom. 14.5).

[Gal 4:10-11 NLT] 10 You are trying to earn favor with God by observing certain days or months or seasons or years. 11 I fear for you. Perhaps all my hard work with you was for nothing.
