All you've done is stated an anecdote, put forth some scenario, elaborated on it in your own way of thinking, which has no bearing on the truth in the word of God. Do you understand this, that you've just provided an opinion piece of your own thinking? There's no mention of the Holy Spirit in your thinking, as if the most important aspect of the believer isn't even in the equation? Yes, you need to seek better revelation on this. I'd suggest, if you're truly interested, Google those who teach eternal security as truth, which is every Spirit-filled scholar of unblemished repute I can think of. This is mainstream Reformed Christianity, over the generations. Read everything there is about it: if you have the Spirit, you'll see the truth.
