The conjunction gar ('for') is the primary causal and explanatory connective in New Testament Greek, introducing the reason, ground, or further explanation for what has just been stated. It stands behind some of Scripture's most consequential explanations: 'for God so loved the world' (John 3:16), 'for all have sinned' (Rom 3:23), 'for the wages of sin is death' (Rom 6:23). Appearing 1,047 times, it is one of the most frequent function words in the Greek New Testament. Spanish porque, French car, and German denn each capture its explanatory force cleanly, and the cross-lingual uniformity confirms a single coherent sense.
