“So he made an excuse, “Let me first go and bury my father.” He most likely appealed to the Jewish burial practice of ossilegium, or secondary burial, which would remove him from following the Lord for up to eleven months (emphasis mine). Jesus saw this as an excuse not to minister to the Gentiles. As a result He rebuked him with a statement of irony and challenged the disciple to follow Him. Quite possibly this was Peter because he is known to have had a problem associating with Gentiles (Acts 10:9-22; Gal. 2:11-12).”
Are you looking for a “leave of absence” for the work of the kingdom? You might have to reconsider that statement in the light of Jesus’ rebuke.
