What Isaiah wrote about was what came from God. He therefore wrote what God showed him so all future readers of the Bible would develop a trust in God. There was at one time a growing concern on the part of Israel concerning false prophets. In Deuteronomy 18, Moses had revealed that there was coming a prophet in the future like him (Deut. 18:15). This Prophet was to be listened to by all the followers of God. The question then being raised was how can we know who the true prophet is? The answer came back in verses 21,22. If a man says that something was going to happen and it did not, then he was a false prophet.
If what Isaiah wrote about, as having come from God, if it did not happen then Isaiah would have been a false prophet. If what he wrote did come to pass then he was a true prophet. The book of Revelation reveals that the testimony of Jesus was the spirit of prophecy (Rev. 19:10). If the life of Jesus did not match up with what the prophets wrote then He was not the Messiah and we are still looking today. The very life of prophecy hinges on the foundation that what we read about Jesus (testimony) was verified in the life of Jesus.
Isaiah saw events that would occur in the “last days”(Isa. 2:2). If there are last days then logically we would conclude there are no days after that. If there is a “church” age followed by a “kingdom” age then the words “last days” would refer to both events. What if the Bible shows us that the last days seen by Isaiah were things that occurred in the first century? If the church and the kingdom are the same thing then once they are here you have the last days and nothing to follow. The religious world must therefore separate the church and the kingdom as being two separate things. Why not take the time to observe what Isaiah saw.
He saw the exalting of the Lord’s house above all others (Isa. 2:2). Jesus was said to be the Son over His own house (Heb. 3:6). That house was the church according to verse 6. Jesus promised to build His church (Matt. 16:18). What if what a prophet said was going to happen and it did not happen? Then according to Deut. 18:22, he was a false prophet. Jesus promised to build His church and later He is described as a Son over His own house that is the church. The testimony of Jesus is the spirit of life of prophecy. Paul addressed the church as being the house of the living God ( I Tim. 3:15). This makes then what Isaiah saw as being valid or right.
Was the church exalted above all else? Paul declared that the Father would receive glory through Jesus the Christ. How would He receive the glory? The answer is through the church (Eph. 3:21). Jesus promised to build the church. He is the Son over His own house that is the church. God receives glory through the church as men live for His Son. Jesus shows us that the church is His body (Eph. 1:22,23). What is it that Jesus will save? He will save His body that is the church (Eph. 5:23). Where are all spiritual blessings but in the church (Eph. 1:3)? Would this not cause reasonable minds to conclude that nothing is more important than the church that tbrings glory to God the Father?
Jesus, in trying to calm the fears of those in His days on earth, warned against not trusting God. He used the example of birds and of flowers to show the care God manifested toward them. If God cares for birds and flowers, surely He will care for you? Jesus wanted them to have faith in God. How would that faith be manifested? Here is how Jesus sums it up. Make your life a seeking of the kingdom of God and His righteousness (Matt. 6:33).
Oh, but we do not understand do we? You see, the church and the kingdom are two different things, according to the religious world. Why then would Jesus use the words of seeking the kingdom first? If the kingdom was not in their lifetime then where is the motivation to seek it first? We seek it first because the church and the kingdom are the same thing that its existence has the purpose of bringing glory to God.
