And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him. Colossians 3:17
Did you know your name has been changed? It's no longer the same as it was before you were born again. You gave your old name away when you made covenant with Jesus.
To fully appreciate what that means, you have to think about it in the light of what we know about blood covenant. When someone enters a covenant of blood, he is giving himself completely away. He is no longer his own. His assets and his debts, his strengths and his weaknesses belong forever to his covenant brother.
When you're in blood covenant with someone, that person's name becomes your name forever. You cannot escape it—good or bad—it's yours.
When you received Jesus as your Lord and Savior, He took your name! Your name was sin. Your name was weakness. Your name was fear and poverty and every other evil thing you inherited from Adam.
Jesus took those names from you and gave you His own in exchange. That's right! Ephesians 3:15 says that the whole Body of Christ has been named after Him both in heaven and earth. That means you have been given Jesus' Name. Its authority is now yours!
Just think about who you're named after:
"Jesus, Mighty God, Wisdom, Deliverer, Lion of the Tribe of Judah, Word of Life, Advocate, Provider, The Great I Am, Helper, Savior, Prince of Peace, Wonderful Counselor, Lamb of God, Lord of Hosts, Root of David, Author and Finisher of Our Faith, The Way, Healer, Son of God, The Truth, Chief Cornerstone, King of Kings, Light of the World, Chief Shepherd, My Strength and Song, Righteous Judge, Son of Righteousness, Resurrection and Life, The Alpha and Omega."
Praise God, those names cover any need you'll ever have. What's more, the power of God is in His Name to bring that Name to pass in your life (Acts 3:16).
You can't call yourself discouraged anymore. That's not your name. You can't answer when the devil yells, "Hey, poor boy." That's not your name. Jesus has taken those old names of yours. They're gone. So meditate on the names of the Lord. They're all wrapped up in the Name of Jesus, the Name above all names, and that Name with all its power and authority has been given to you!
Ephesians 3:16-21 New Living Translation
16 I pray that from his glorious, unlimited resources he will empower you with inner strength through his Spirit. 17 Then Christ will make his home in your hearts as you trust in him. Your roots will grow down into God’s love and keep you strong. 18 And may you have the power to understand, as all God’s people should, how wide, how long, how high, and how deep his love is. 19 May you experience the love of Christ, though it is too great to understand fully. Then you will be made complete with all the fullness of life and power that comes from God. 20 Now all glory to God, who is able, through his mighty power at work within us, to accomplish infinitely more than we might ask or think. 21 Glory to him in the church and in Christ Jesus through all generations forever and ever! Amen.
