God demands righteousness, and when man fails to meet His standards, He calls for the shedding of blood for the remission of sins (Hebrews 9:22). Throughout the Old Testament, sacrifices majored on the blood of animals, but these animal sacrifices could never take away sins (Hebrews 10:4). God, in mercy, sent His Son to give “himself for us an offering and a sacrifice to God for a sweetsmelling savour” (Ephesians 5:2). Unlike the Old Testament sacrifices, the Lord Jesus was a single onetime sacrifice that offered forgiveness of sin for all and to all. In shedding His blood, the Lord Jesus Christ became man’s sacrifice, and man need look no further than the shed blood of Christ for the means by which God is satisfied.
In Bible times, cities would often build towers to watch the gates to avoid dangers looming from without (Isaiah 21:8). Watchmen would take turns watching the gate. These watchmen were responsible for sounding a trumpet should any danger appear (Ezekiel 33:6). The apostle Paul in his writings applied a spiritual application to this literal act of being a watchman. Just as cities needed men willingly staying awake and alert while others slept or were busy in their daily routines, churches need believers sober and watchful while others might be cumbered about with the cares of this world. Today’s watchmen must use their voices like a trumpet to sound the alarm when danger nears.
