It is true that many scriptures exhort us to spiritual exercises on a daily basis : prayer, worship and the care of our fellow human beings.
And it is true that Jesus Christ himself exhorts to continued and increased devotion and maturity in the faith. I am thinking, here, of the seven letters written to seven churches which express deep concern for the daily walk and pilgrimage of every member of the body of Christ.
But no scripture I can think of and no group or gathering I have ever come into contact with, in the past fifty five years of my own Christian profession (I am in my seventies) has ever expressed the need of being 'saved every day' nor have I ever read, in Church history of such a doctrine.
This undermines the work of God in the soul. It undermines justification by faith, which is God's work (to justify) and the Holy Spirit's work (to bring to repentance and to faith).
We are not saved by works, by decisions, by assertions, by acceptances nor by commitments or promises or oaths or covenants of our own.
... For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: [Ephesians 2:8 KJV]
