"And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him." (Colossians 3:17)
The verse above is quite instructive: it says, "whatever"; that means that, anything you do, whether it's in word or in deed, it should be in the Name of the Lord Jesus Christ. Why? Because you're in Him-- you're born of Him!
"I am the vine, you are the branches..."
(1 Corinthians 6:17)
"But he who is joined to the Lord is one spirit with Him."
We're in an inseparable union with Him. Your conduct, manner of life, and character should always reflect Him, because you're His icon-- you represent Him.
Christ should, and must, be seen and heard in you. Jesus said "He that has seen me has seen the Father" because He epitomized the Father. He was the Father's reflection, His glory, the express image of His person (Hebrews 1:3). Today, you live in the earth, and do whatever you do as a representative of Jesus. You function in His Name.
So, live and talk as a God-man. This consciousness brings a different perspective to your character. Read our theme verse again: it says live, talk, and conduct your life in the Name of the Lord Jesus! Think about it: how many hurtful or abusive remarks could we make in His Name? None! How much untoward conduct can you display in His Name? None! When you talk and act in the Name of Jesus, the result is excellence. He'll be heard in your speech and seen in your actions.
Live every day as a conscious representative of Jesus Christ. Never forget who you are-- don't take a vacation from your identity with Him. Let your Christ-character be consistent wherever you go. When you're in church, at the office, or any other place, your communication and actions should be the same-- gracious, kind, and excellent-- in the Name of the Lord.
I'm an ambassador, a conscious representative of Jesus Christ, living in His Name! My communications and actions aptly depict my union and oneness with the Lord. And as God's Word gets into my spirit, I'm transformed into the same image, from glory to glory, by the Holy Spirit. Hallelujah!
