God doesn’t want perfect vessels only yielded ones, I think what he’s trying to tell us is that perfect vessels don’t really think they need help. It’s comparable to the parable he tells the disciples if there is a sick man but he doesn’t believe he sick how will he ever know or come to get help? The answer is he won’t because he doesn’t think there’s a need so that’s why he said I didn’t come for those who are healthy, but those who are sick. Luke 5:31 That’s not to say that he didn’t come for all of us to be forgiven to receive everlasting life it is in his desire that none should perish. He’s only giving us understanding that until a man understands he sick he won’t seek help.
