One person may consider one day to be more sacred than another, while another may judge all days to be alike. Let everyone be convinced in his own beliefs.
In the same way, some think one day is more holy than another day, while others think every day is alike. You should each be fully convinced that whichever day you choose is acceptable.
I give them eternal life, and they will never perish. No one will ever snatch them from my hand. My Father who has given them to me is greater than all, and no one can snatch them out of the Father’s hand. I and the Father are one.
