" But because Peter had eternal assurance, he was in no danger of losing what was given to him from the One who knit him together in His mother’s womb. The reason? It wasn’t Peter’s ‘sinful’ hold of Jesus that assured him of his salvation, it was Christ’s ‘sinless’ hold of him. “Sadly, even after we are saved, just like Peter, we will still sin and fall short of the glory of God too many times to count. The simple truth is, we’re not sinners because we sin, we sin because we’re sinners. "
