What does Isaiah 1:14 mean?
God is tired of observing the worship practices of His people while their hearts are estranged from Him (Isaiah 1—4). He uses harsh language, saying that His soul hates their observances and other law-required feasts. It's not that God did not want them to obey the requirements of the law for those things. Obedience to the law has no meaning if their hearts were hard and their daily lifestyles were continually sinful.He finds their acts of worship to be a burden for Him, because their hearts and minds are not for Him. Instead of receiving the praises of His people with joy, He is tired of carrying them because they are false, dead weight.
