God’s Name Is the Measure of Our Sin and His Salvation (Exodus 20:7)

How does one take the name of God in vain? Let’s reflect on one obvious answer: oaths. One profanes God’s holy name, not by taking oaths, but by taking them falsely. “You shall not swear by my name falsely, and so profane the name of your God: I am the LORD (Leviticus 19:2).” Many recall Jesus’ words in the Sermon on the Mount and think we shouldn’t swear at all, but this loses the real significance of what He was saying and contradicts both the Old and New Testaments.

“You shall fear the LORD your God. You shall serve him and hold fast to him, and by his name you shall swear (Deuteronomy 10:20).”

“For God is my witness, whom I serve with my spirit in the gospel of his Son, that without ceasing I mention you (Romans 1:9).”

“For God is my witness, how I yearn for you all with the affection of Christ Jesus (Philippians 1:8).”

So what was Jesus’ speaking of when He said:

Again you have heard that it was said to those of old, ‘You shall not swear falsely, but shall perform to the Lord what you have sworn.’ But I say to you, Do not take an oath at all, either by heaven, for it is the throne of God, or by the earth, for it is his footstool, or by Jerusalem, for it is the city of the great King. And do not take an oath by your head, for you cannot make one hair white or black. Let what you say be simply ‘Yes’ or ‘No’; anything more than this comes from evil (Matthew 5:33–37).

If you couple this with what Jesus later says concerning oaths I think you’ll get a clearer picture:

Woe to you, blind guides, who say, ‘If anyone swears by the temple, it is nothing, but if anyone swears by the gold of the temple, he is bound by his oath.’ You blind fools! For which is greater, the gold or the temple that has made the gold sacred? And you say, ‘If anyone swears by the altar, it is nothing, but if anyone swears by the gift that is on the altar, he is bound by his oath.’ You blind men! For which is greater, the gift or the altar that makes the gift sacred? So whoever swears by the altar swears by it and by everything on it. And whoever swears by the temple swears by it and by him who dwells in it. And whoever swears by heaven swears by the throne of God and by him who sits upon it (Matthew 23:16–22).

Here are two related errors: 1. excessive oath taking and 2. thinking only some oaths are binding. Whatever other factors there are, this is clear, they aren’t taking oaths seriously. God commanded that when they swore, they were to swear in His name (Deuteronomy 10:20), and therefore, when they swear, it  must be with the utmost seriousness and reverence.

Further, when a child of God swears by anything, He swears by God’s name, for everything is God’s, all our life is lived Coram Deo (before God’s face), and His name is ever upon us. This means that we can profane the name of YHWH not just with oath words, but with all words and all actions. His name is on us. We bear His name as a wife bears her husband’s. God in covenant love has set His name upon us. How we live reflects on His name (Deuteronomy 28:9–10). God’s children never put down God’s name, even when they put it down.

We are guilty and God doesn’t let this sin fly. Paradoxically, and gloriously, our only hope for blaspheming God’s name, is God glorifying His name. God chose to magnify the glory of His name, by exalting the name of Jesus above all other names, in His redeeming sinners who have blasphemed His name, through Jesus’ perfectly revering God’s name for them, and suffering for their every taking of God’s name in vain.

All praise be to His holy name.

God’s Name (Exodus 3:13–22)

But Moses said to God, “Who am I that I should go to Pharaoh and bring the children of Israel out of Egypt?” He said, “But I will be with you, and this shall be the sign for you, that I have sent you: when you have brought the people out of Egypt, you shall serve God on this mountain.” Then Moses said to God, “If I come to the people of Israel and say to them, ‘The God of your fathers has sent me to you,’ and they ask me, ‘What is his name?’ what shall I say to them?” —Exodus 3:11–13

Moses: Who am I?

God: But I will be with you.

Moses: Ok. Not me. You. Got it. …Who are you?

God: I AM WHO I AM.

God has addressed Moses by name. Moses has not returned the favor. Was God’s name not known up to this point? No. The name of God is YHWH or Yahweh, represented every time we see the all caps “LORD” in the Old Testament. Knowing this, we see that Abraham knew this name (Genesis 12:8), as well as Isaac (Genesis 26:25), and Jacob (Genesis 28:16). We can go all the way back to the third generation of man (Genesis 4:26). God’s name was known.

Has Moses been baking in the wilderness too long? Or has the 400 year bondage caused him, along with all Israel, to forget? A better answer is found in a couple of verses that may initially cause us more puzzlement. “God spoke to Moses and said to him, ‘I am the LORD. I appeared to Abraham, to Isaac, and to Jacob, as God Almighty, but by my name the LORD I did not make myself known to them (Exodus 6:2-3).’” So was Genesis mistaken? Did the patriarchs not call upon YHWH? They knew the name YHWH, but YHWH wasn’t known by His name. God had appeared and made himself known as God Almighty, but His name YHWH was a mystery to them. Now, God is revealing Himself in His name to Moses so that he might give it to His people.

Biblically, names are revelatory. They’re meaningful. God’s name communicates His aseity, immutability, incomprehensibility, transcendence, simplicity, and holiness. But His name also represents His condescension. In giving this name, God is stooping and lisping to His children. To know God’s name isn’t just to know Him, but to know Him intimately. This is God’s covenant name that His people are to remember Him by (Exodus 3:15).

It’s a shame that we’ve forgotten it. We read that Abraham “called upon the name of the LORD,” and think of a title, “Lord,” instead of a personal name, “YHWH.” It’s a great shame that we don’t call upon this name. It’s a greater shame that we forget Who it is this name says we call upon. Pray to your Father, but do not forget that it is YHWH—the self-existent, transcendent, holy, immutable I AM come down in covenant love—that you call upon as Father.

By God’s grace we do better than we know. Anytime we call upon the name of Jesus, truly knowing Him as the supreme revelation of God, we are leaning upon the truth revealed in God’s name—the Holy one, come down in covenant love to redeem His people. “Jesus” is the Greek equivalent of the Hebrew “Joshua” or “Yeshua”  which means “YHWH is salvation.” The angel commanded Joseph “to call his name Jesus for he will save his people from their sins (Matthew 1:21).” God told Moses that God would deliver His people (Exodus 3:8). Unlike Moses, with Jesus, God isn’t simply delivering His people through a man; Jesus is God come to deliver His people. He is YHWH, and so He says, “before Abraham was, I am (John 8:58).” Knowing the name of YHWH helps us to better understand the name of Jesus. May we never forget, throughout all our generations.
