This section of Isaiah begins with a lesson on fasting and keeping the Sabbath day holy. Isaiah scolded the Israelites for complaining and showing how miserable they were when they were fasting. Isaiah taught that the purpose of fasting isn’t to make you unhappy, it’s to bring blessings to you and others. Fasting should include feeding the poor, praying, and focusing on the Lord and His guidance. Sabbath day worship should also be a delight. Isaiah taught that we should not seek our own ways or our own pleasure on the Sabbath, but to instead delight ourselves in the Lord. It’s important to take time to find joy, peace, and gratitude for the Lord on the Sabbath day.

Isaiah also spoke again of the Second Coming of the Messiah. He warned about the destruction of the wicked and rejoiced in the salvation of the Lord’s people. He taught about the peace that will exist on the earth after Jesus comes.
