Baptism separates the tire kickers from the car buyers.

Using a car-lot metaphor, Lucado frames baptism as a decisive, public step that distinguishes casual interest (“tire kickers”) from committed follow-through (“car buyers”). The image suggests that many people may admire Jesus, explore Christianity, or enjoy church culture without embracing the costly, identity-shaping commitment of discipleship. In this reading, baptism functions less as a mere ritual and more as a threshold act: a concrete, embodied declaration of allegiance that moves faith from private inclination to visible participation in the Christian community. The line also implies pastoral urgency—inviting hearers to move beyond spectatorship into lived obedience.
