In this word picture the cart represents the works of man. The horse represents salvation.

Do you have the cart before the horse?

Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing* of regeneration**, and renewing of the Holy Ghost; Titus 3:5

And you hath he quickened (made alive), who were dead in trespasses and sins; Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:

Among whom also we all had our conversation (manner of life) in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.

But God, who is rich in mercy, for his great love wherewith he loved us,  Even when we were dead in sins, hath quickened us (made us alive) together with Christ, (by grace ye are saved;)

And hath raised us up together, and made us sit together in heavenly places in Christ Jesus: That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.

For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.

For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.       Ephesians 2:1-10

…let the word of Christ dwell (take up its life) in you richly…

*Husbands, love your wives, even as Christ also loved the church, and gave himself for it; That he (Christ) might sanctify and cleanse it (the church) with the washing of water by the word…….Ephesians 5:25&26.

**Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.  I Peter 1:23
