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]
Those who have repented, believed the gospel of Jesus Christ, the Son of God and who 'continue in the apostles' doctrine and fellowship and in breaking of bread and prayers', Acts 2:42, have ' already been delivered from the wrath to come' , 1 Thessalonians 1:10, and we look, in hope and in love, for his promised return.
I was baptised into the presbyterian Church of Scotland at the age of five (I remember the event) and I volunteered for baptism, again, as an adult, at the age of sixteen, into the Baptist Assembly of Scotland.
My evangelical testimony, written at the age of twenty-one in 1972 (and published in 1992) is freely available on my website. See my profile for the website details.
