I am really not getting this analogy!
I live in Canada! We have to change our tires twice a year - all 4 of them. From summer to winter, and winter to summer.
My son-in-law is a brilliant doctor and he changes his tires. My father was a dumb jock with a Ph.D and he changed his tires. My husband is a handyman and he changes his tires.
But a flat? Even my husband takes it to the tire garage. Because you need special equipment to get it off the rims. So, what is your point?
As for light bulbs?? Who gets a handyman to do that? I am disabled, and I change lightbulbs all the time. Handy hubby let the shoemaker's children go barefoot, sometimes, unless I beg him, on lights that are up high!
But, your whole premise concerning soteriology is wrong! All you end up is with a legalist, obeying the law on the outside, with no change on the inside. What did Jesus say?
"Jesus replied, “I tell you the solemn truth, unless a person is born from above, he cannot see the kingdom of God.” 4 Nicodemus said to him, “How can a man be born when he is old? He cannot enter his mother’s womb and be born a second time, can he?”5 Jesus answered, “I tell you the solemn truth, unless a person is born of water and spirit, he cannot enter the kingdom of God. 6 What is born of the flesh is flesh, and what is born of the Spirit is spirit." John 3:3-6 NET
The words "born from above" is correctly translated in this version. It is not "born again" in this place, where Jesus says it. Although, Nicodemus sure got it wrong! He thought Jesus WAS saying "born again." But Jesus was talking "from above." The word in Greek is anothenἄνωθεν and it means both "from above" and "again."
But Jesus wasn't talking about going back into his mother's womb at all! He wasn't talking about being born a second time. Jesus was talking about being born from above! Being born of the spirit. But, if you want to say "born again" it can actually work too! Except you have to remember that being born again, means being born of the spirit from above!
So, let us use this analogy instead of clumsy metaphors about turtles and flat tires! Jesus says the start of our journey is the spirit changing us from the inside out. There is no decision to make! God does the work!
And that work is powerful! It changes us in a way that we KNOW has happened! We want to obey God! We want to repent of our sins! We want to walk with God the rest of our days!
That is why I am a monergist! Because, no, I never made a decision! God just changed me, in an instant! And the first thing he told me was I needed to repent of my sins! And to read the Bible! Which was so strong, such a command I didn't dare disobey, I have been reading and studying the Bible ever since! That was May, 1980!
In my own strength, I could not make a decision. My heart was hard! My mind was turned to the world! But God stopped me in my tracks! His Spirit changed my spirit! Then, I had the ability to follow God, which I could not in my own strength. I was born from above.
A dead person cannot make decisions about what it is going to do. Before God saves us, we are dead people. Eph. 2 makes this very clear!
"And although you were dead in your transgressions and sins, 2 in which you formerly lived according to this world’s present path, according to the ruler of the kingdom of the air, the ruler of the spirit that is now energizing the sons of disobedience, 3 among whom all of us also formerly lived out our lives in the cravings of our flesh, indulging the desires of the flesh and the mind, and were by nature children of wrath even as the rest…
4 But God, being rich in mercy, because of his great love with which he loved us, 5even though we were dead in transgressions, made us alive together with Christ—by grace you are saved!—6 and he raised us up with him and seated us with him in the heavenly realms in Christ Jesus, 7 to demonstrate in the coming ages the surpassing wealth of his grace in kindness toward us in Christ Jesus. 8 For by grace you are saved through faith, and this is not from yourselves, it is the gift of God; 9 it is not from works, so that no one can boast. 10 For we are his workmanship, having been created in Christ Jesus for good works that God prepared beforehand so we may do them." Eph. 2:1-10
Verse 5 says it all! We were dead in our sins, and God made us alive in Christ. No obedience before, no decisions, God made us alive with Christ! Why? Because of his grace! Amazing!
