The word Lord should not be used carelessly. It’s unacceptable to speak of Jesus as Lord in our conversations and prayers but then to contradict the claim by defying His will and His Word. A lot of believers probably think that statement doesn’t apply to them. But we should all realize resistance can be subtle—perhaps by qualifying our obedience with conditions like “I’ll follow the Lord if ...” or “I want to do what is right, but ...”

When Jesus is identified as Lord in the Scriptures, it signifies that He is the sovereign ruler over life and all creation. When we assert that He’s our Lord, we’re claiming that He is our Savior and Master, which means we submit to Him in all things. If we attest to this verbally but don’t actually do what Jesus says, then are we really serving Him?

None of us can obey Christ perfectly, but once we’re born again, submitting to Him should be our heart’s desire and our practice. After all, He purchased us with His precious blood and now rules over us for our good. So, though we may struggle at times, our lives should be characterized by obedience to our Lord because we are His.

Luke 6:46-49
New International Version
The Wise and Foolish Builders
46 “Why do you call me, ‘Lord, Lord,’ and do not do what I say? 47 As for everyone who comes to me and hears my words and puts them into practice, I will show you what they are like. 48 They are like a man building a house, who dug down deep and laid the foundation on rock. When a flood came, the torrent struck that house but could not shake it, because it was well built. 49 But the one who hears my words and does not put them into practice is like a man who built a house on the ground without a foundation. The moment the torrent struck that house, it collapsed and its destruction was complete.”
