‘Bastard’ isn’t meant to be a swear word, it describes someone without a father.
The King James version uses the term (in Hebrews 12:8) to describe those who don’t receive correction or discipline. (both key ingredients of discipleship)
Although this passage refers to the spiritual son (or daughters’) attitude / responsibility in RECEIVING correction and discipline …
… it also implies that legitimate fathers OFFER correction and discipline. (again, ingredients of true discipleship)
As the passage tells us … This is how a son is “RECEIVED” and “LOVED” and made “LEGITIMATE” – (both natural and spiritual sons)
To be true fathers, there’s no excuses and no shortcuts. Theories and second-hand lessons won’t cut it. Sons want more from us, they want the real deal.
