A racecar is a very fast car that is used in professional auto racing. Biblically, a racecar could represent the good fight of faith.
Positive: To dream of racing in a car could represent that you are overcoming a trial through the help of God. Dreaming of a racecar speeding could symbolize that you are accelerating quickly in the Spirit.
Negative: Dreaming of a racecar could symbolize that you are moving too fast and not paying attention to the things around you. It could also represent that you are doing your own thing and not following God’s direction.
(Galatians 2:2; 2 Timothy 4:7; 1 Corinthians 9:24-27; Philippians 3:14).
