Either Jesus is a liar, meaning all of the claims He made concerning himself (i.e. "I am the way, and the truth, and the life. No one comes to the Father except through me." ~ John 14:6) and all the wonders He did (healed the blind, lame, mute, deaf, raised the dead... you know... nothing big) were all well fabricated deceptions and empty words. Or, Jesus is a lunatic, meaning He was demented and not functioning right in the head. Or, Jesus is LORD, meaning all He claimed was true, all He did was real, and Jesus Christ really is the Son of God come to the world to save sinners. If He was simply a good teacher or a prophet, then it would naturally follow that what He said was true, including all that He said about Himself and His relationship with God... hence, making Him Lord.

We earnestly believe Jesus is LORD. The word LORD really means master, showing us that He doesn't simply want your recognition, He aims to be master​ of your life! When Jesus called to the disciples, He didn't ask them to repeat a prayer or start going to church. Jesus said to them, "Follow me, and I will make you fishers of men" (Matt. 4:19 ESV). The disciples, in response, "Immediately... left their nets and followed him" (Matt. 4:20 ESV). The disciples left their jobs, their homes, their families, their lives behind in order to follow Jesus. In the same way, Jesus is calling to each one of us to follow Him. For us, to follow Jesus means to abandon all worldly pursuits and pleasures, declare them as vanity, deny our(self), value Christ above all else, take up our cross, and follow Jesus.
