The Saint’s White Raiment only obtained in Christ: is unspotted by works of our flesh.
In my estimation, we only have two choices in how to walk “in Christ” ; we either realize our utter dependency on “Christ’s work alone” within our lives, or we attempt and apply a type of legalism in achieving a superior walk toward perfection, while “using” the Holy Spirit’s assistance.
To the natural understanding within our souls, this may look to be a good option. Yet I firmly believe, this is like taking something blemished and stained of the flesh, and attaching it to an unblemished and unstained article yet expecting it to remain pure.
No place which I’m aware of in the Bible speaks of taking a filthy rag and then laundering it with an unstained garment.
