(Luk_6:46 and Mat_28:19-20)
The scriptures often emphasize the fact that Jesus is our Lord. The opening verses of Paul's first letter to Corinth are a clear example. "Paul . . . to those who are sanctified in Christ Jesus . . . with all who in every place call on the name of Jesus Christ our Lord . . . Grace to you and peace from God our Father and the Lord Jesus Christ . . . you come short in no gift, eagerly waiting for the revelation of our Lord Jesus Christ . . . who will also confirm you to the end, that you may be blameless in the day of our Lord Jesus Christ. God is faithful, by whom you were called into the fellowship of His Son, Jesus Christ our Lord. Now I plead with you, brethren, by the name of our Lord Jesus Christ" (1Co_1:1-10).
Clearly, it is right for followers of Jesus to call Him Lord. Yet, to call Him Lord and then disobey Him is a contradiction. "But why do you call Me 'Lord, Lord,' and do not do the things which I say? " After believing in Jesus and identifying with Him in water baptism, disciples are to be growing in obedience: "teaching them to observe all things that I have commanded you." As we are learning to walk in obedience, Jesus is ever present with us. "I am with you always." Day by day, He offers the grace we need for obedience: "Declared to be the Son of God with power . . . through whom we have received grace and apostleship for obedience to the faith" (Rom_1:4-5).
