The prophet Micah wrote regarding a prophesy of the coming of the Lord’s church and the nature of the church and concluded by saying, “for the mouth of the Lord of hosts has spoken” (Micah 4:4). That phrase, “the mouth of the Lord”, is very powerful because the implication is that whatever the Lord has spoken then it will come to pass. The Lord said through Micah regarding the coming of the church “But in the last days it shall come to pass, that the mountain of the Lord’s house will be established in the top of the mountains, and it shall be exalted above the hills, and people shall flow unto it. Any many nations shall come…for the law shall go forth from Zion and the word of the Lord from Jerusalem” (Micah 4:1-2).
The Lord’s church did come into existence in Zion or Jerusalem on the day of Pentecost as the apostles preached the gospel in that city and on that day (Acts 2). The church of Christ came into existence in the last days because as the author of Hebrews wrote, “God…has in these last days spoken unto us by his Son, whom he has appointed heir of all things, by whom also he made the world” (Hebrews 1:1-2). The nature of the church was prophesied in that “and many nations shall come…” (Micah 4:2). The book of Acts reveals how the gospel went forth from Jerusalem to Judea, Samaria, and into all of the world (Acts 1:8), and people of all nations obeyed the gospel of Christ. The church is universal and spiritual in nature. There are no borders in the church for all that have obeyed the gospel have been added to the Lord’s church (Acts 2:47). To all of this Micah concluded by writing, “for the mouth of the Lord of hosts has spoken”. The Lord has spoken about this and many other things that relate to our spiritual lives.
The Lord has spoken about what kind of people that should be. Peter wrote, “But as he which called you is holy, so be you holy, in all manner of conversation (life), because it is written, Be you holy for I am holy” (1 Peter 1:15-16). Holiness and godliness are to be the quality and character of a child of God. The Lord has spoken concerning the kind of fruit that Christians are to produce. “But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, meekness, temperance, against such there is no law” (Galatians 5:22-23). The Lord has spoken concerning our character and the fruit that should be produced by us. In contrast the Lord has spoken about the works of the flesh that should not be found in our lives or hearts (Galatians 5:19-21).
The Lord has spoken about the certainty of death and the judgment to come. “And as it is appointed unto men once to die, but after this the judgment” (Hebrews 9:27). Death is not optional because it will come to us. The option that we do have is whether or not we will conform our lives to God’s will and be prepared for the day of judgment. The mouth of the Lord has spoken regarding death and the judgment. God has provided all that we need pertaining to life and godliness (2 Peter 1:3), but what will our decision be? The phrase “the mouth of the Lord has spoken” is powerful because God’s word has always come to pass and will continue to do so. “But the day of the Lord will come as a thief in the night…” (2 Peter 3:10). The day of the Lord and the judgment to come will be a joyous day or a sorrowful day depending upon our present decision. “For the mouth of the Lord of hosts has spoken.”
