The big problem is that too much emphasis is placed on the outward appearance of a man rather than the interior truth of his being. Sure it might look to all the world as if there is no sin and therefore proof oh his salvation is assured but we can never see what Christ sees.
Salvation is an ongoing journey. It is through grace which God freely gives even when we sin again. No matter how many times we fall, He will reach down for us. No matter how often we stray, He will seek us out. Our outward perfection means nothing to Him. It is a contrite and humble heart that seeks Him above all else that most gives Him pleasure. He is mercy.
If we sin after knowing HIm it does not mean His grace wss never within us, it means we keep proving again and again the reason for the Cross.
AMEN!!!
Although, I would say that the salvation is a done deal but walking it out, growing in the grace and knowledge of Christ and becoming ever more conformed to His image, is an ongoing journey.
We are not perfect when we are saved, but we are saved. The perfecting part is what takes time and none of us ever reach it here on earth.
