Jesus Christ is Lord
If you declare with your mouth, "Jesus is Lord," and believe in your heart that God raised him from the dead, you will be saved. (Romans 10:9)
"Jesus is Lord" is the confession of every Christian because it is foundational to our faith. In order to be saved, the apostle Paul says we must confess with our mouth Jesus as Lord (Romans 10:9). Such doctrine is central to Christianity, and all who are devoted followers of Jesus Christ believe that He is Lord of all creation and all time.
However, when we say "all", it means us as well. If Jesus truly is the sovereign Lord of heaven and earth, then He is also the Master of our individual lives. Christ's sovereign rule is not limited to governing the vast universe; it is also a personal issue. He is Lord of our normal, daily lives - our choices, priorities, activities, attitudes, words, everything.
Paul captured this truth in Romans 14:8 when he wrote, "If we live, we live for the Lord; and if we die, we die for the Lord." The apostle considered it impossible to compartmentalize Christ's lordship. He knew his life belonged wholly to Jesus.
Jesus doesn't want to be only part of our life; He made that clear with His disciples. When we give the Lord just a portion, then we are telling Him there are other things we consider at least as important as He is. Do you know what the Bible calls this? Idolatry.
Jesus never called people to give Him a try. He demanded full surrender: "Whoever wants to be my disciple must deny themselves and take up their cross daily and follow me." (Luke 9:23). We can't squeeze Jesus into one segment of our life and continue living as we please. If we are truly His, then Jesus is our life.
