In Luke 13 and 14, along with so many other places, Jesus points to the impossibility of our fleshly selves following after Him. Here's just two sections:
So he went on his way through towns and villages, teaching as he went and making his way towards Jerusalem. Someone remarked, “Lord, are only a few men to be saved?” And Jesus told them, “You must do your utmost to get in through the narrow door, for many, I assure you, will try to do so and will not succeed, once the master of the house has got up and shut the door. Then you may find yourselves standing outside and knocking at the door crying, ‘Lord, please open the door for us.’ He will reply to you, ‘I don’t know who you are or where you come from.’ ‘But ...’ you will protest, ‘we have had meals with you, and you taught in our streets!’ Yet he will say to you, ‘I tell you I do not know where you have come from. Be off, you scoundrels!’ At that time there will be tears and bitter regret—to see Abraham and Isaac and Jacob and all the prophets inside the kingdom of God, and you yourselves excluded, outside! Yes, and people will come from the east and the west, and from the north and the south, and take their seats in the kingdom of God. There are some at the back now who will be in the front then, and there are some in front now who will then be far behind.” From Luke 13
Now as Jesus proceeded on his journey, great crowds accompanied him, and he turned and spoke to them, “If anyone comes to me without ‘hating’ his father and mother and wife and children and brothers and sisters, and even his own life, he cannot be a disciple of mine. The man who will not take up his cross and follow in my footsteps cannot be my disciple. If any of you wanted to build a tower, wouldn’t he first sit down and work out the cost of it, to see if he can afford to finish it? Otherwise, when he has laid the foundation and found himself unable to complete the building, everyone who sees it will begin to jeer at him, saying, ‘This is the man who started to build a tower but couldn’t finish it!’ Or, suppose there is a king who is going to war with another king, doesn’t he sit down first and consider whether he can engage the twenty thousand of the other king with his own ten thousand? And if he decides he can’t, then, while the other king is still a long way off, he sends messengers to him to ask for conditions of peace. So it is with you; only the man who says goodbye to all his possessions can be my disciple." From Luke 14
The Way is literally contrary to the flesh. You and I so often want to "have our way" but that will never, ever be the Way. The only way to "have His Way" is to be a daily, observant, nimble, quick-to-listen, lightning-quick-to-obey follower of the Indwelling Jesus. His Holy Spirit is always able to defeat the whims of the flesh, but it's a battle that must be attended to by attentive followers-of-Jesus!
He is able to keep us on His Way! May we never cease to walk it!
