Revelation 3:12b …And I will write on him the name of my God…
Jesus will write on the believer the name of His God. His name is Yahweh.
The topic of God’s name has been addressed previously to the church at Sardis. God takes the time to repeat the concept of His name to the church at Philadelphia. It bears repeating.
YHWH (scholars refer to this as the Tetragrammaton, Greek for four letters) is the proper name of the Hebrew God of the Bible. The correct spelling is YHWH. Note there are no vowels in this term. Vowels from the name Adonai were substituted and the term Yahweh emerged. Jehovah is a word that has been translated to English from the Hebrew, Yahweh. The name for LORD is Jehovah. It means the existing one. This name is so sacred, Jews refuse to pronounce it. The name is first introduced in Exodus 3:14 when Moses and God are having a discussion. His name is a statement of existence.
Exodus 3:14 God said to Moses, “I AM WHO I AM”; and He said, “Thus you shall say to the sons of Israel, ‘I AM has sent me to you.’”
If one is looking for proof that God created or God exists, you are wasting your time. It is assumed. God is eternal and self-existent. God always has been and always will be. God was before the creation.
Not only does Jesus write the name of Yahweh on the believer, the believer is sealed with the Spirit of God. There are at least 12 verses in the Bible confirming the work of the Spirit in His people.
2 Corinthians 1:21-22 And it is God who establishes us with you in Christ, and has anointed us, and who has also put His seal on us and given us His Spirit in our hearts as a guarantee.
Ephesians 1:13-14 In Him you also, when you heard the word of truth, the gospel of your salvation, and believed in Him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of His glory.
All three persons of the triune God are involved: Father, Son, and Spirit. To borrow a line from Stevie Wonder…
Signed, sealed, delivered, I’m yours.
This name is a promise for all eternity. We see this at the end of Revelation in New Jerusalem. These are the closing comments of the Bible.
Revelation 22:4 They will see His face, and His name will be on their foreheads.
