In these passages, Isaiah prophesies the coming of Jesus to rule from Jerusalem. Isaiah made this prophecy before Jesus came to the Earth the first time. However, it speaks of His second coming.
Jesus came to the earth about 2000 years ago to introduce Himself to the world and to die for the sins of mankind. He will come a second time to rule over the Earth for 1000 years.
Between His first and second coming to the Earth Jesus’ created His Church. Jesus’ Church consists of those people who truly believe in Him. Jesus’ Church is not a structure or a building. Many people attend church services. However, not all who attend are truly members of Jesus’ Church.
The Bible says that only a few will be allowed to enter Heaven. ‘The pathway to Heaven is difficult and the door to Heaven is small. Only a few find the door to Heaven.’ On the other hand, the way to Hell as broad and there are many paths that lead there. Many people follow those paths.
There is only one pathway to Heaven. That is exclusively through Jesus Christ, who is the living Word of God. One could rightly say that the pathway to Heaven can only be found in the Bible, which is the Word of God.
