You won't all off the path after this life

"We don't need to get a complex or get a feeling that you have to be perfect to be saved. You don't. There's only been one perfect person, and that's the Lord Jesus, but in order to be saved in the Kingdom of God and in order to pass the test of mortality, what you have to do is get on the straight and narrow path-thus charting a course leading to eternal life-and then, being on that path, pass out of this life in full fellowship. I'm not saying that you don' have to keep the commandments. I'm saying you don't have to be perfect to be saved. If you did, no one would be saved. The way it operates is this; You get on the path that's named the 'straight and narrow.' You do it by entering at the gate of repentance and baptism. The straight and narrow path leads from the gate of repentance and baptism, a very great distance, to a reward that is called eternal life, If you're on that path and pressing forward, and you die, you'll never get off the path. There is no such thing as falling off the straight and narrow path in the life to come... If you're on that path when death comes--because this is the time and the day appointed, this is the probationary estate--you'll never fall from it, and, for all practical purposes, your calling and election is made sure."
