Isaiah 25 starts with a song of praise, thanking and praising God for the future establishment of His kingdom on earth. “O Lord, you are my God; I will exalt you; I will praise your name, for you have done wonderful things, plans formed of old, faithful and sure … For you have been a stronghold to the poor, a stronghold to the needy in his distress”.
Isaiah describes a time when all will be invited to a feast, much like Jesus’ parables of the kingdom. Death will be swallowed up forever, “and the Lord God will wipe away tears from all faces”. On that day, people will say “Behold, this is our God; we have waited for him, that he might save us … let us be glad and rejoice in his salvation.”
Hebrews 8-9 describes the work of Christ as a sacrifice and high priest, making it possible for us to be part of the future Isaiah wrote about. It’s up to us to respond to God’s calling, to have God’s laws written in our hearts and minds, to be God’s people, knowing that Christ will shortly “appear a second time… to save those who are eagerly waiting for him”.
