The Hebrews were told: “Do not be carried away with various and strange teachings; for it is fine for the heart to be given firmness by undeserved kindness, not by eatables, by which those who occupy themselves with them have not been benefited.”​—Hebrews 13:9.

10. According to Hebrews 13:9, by what is the heart given firmness?

¹⁰ The Hebrews therefore needed to avoid being “carried away with various and strange teachings” of Judaizers. (Galatians 5:1-6) Not by such teachings but ‘by God’s undeserved kindness can the heart be given firmness’ so as to remain steadfast in the truth. Some apparently argued about foods and sacrifices, for Paul said that the heart was not made firm “by eatables, by which those who occupy themselves with them have not been benefited.” Spiritual benefits result from godly devotion and appreciation for the ransom, not from undue concern about eating certain foods and observing particular days. (Romans 14:5-9) Moreover, Christ’s sacrifice made Levitical sacrifices ineffective.​—Hebrews 9:9-14; 10:5-10.
