3 Names to Know

The name, “I am who I am” in Hebrew is the word Yahweh, which we also know as Jehovah. It means self-existent, and it signifies that God has no beginning and will never have an end. This name describes His fullness—His eternal existence, sovereignty, unlimited power, and omnipresence.
There are three basic names for God in the Old Testament. Although we are unable to fully understand everything about the Lord, we can learn more about Him through His names.
Elohim is the name used of Him in Genesis 1:1 and is translated God. It describes Him as existing before the beginning of time and being the Creator of the heavens and earth and all that is in them.
Adonai is the Hebrew name translated Lord and simply means Master.
Yahweh or Jehovah is the most sacred and precious name of God used among His people, often in association with Abraham, Isaac, and Jacob. It’s usually signified in the Old Testament with the word Lord written in all capital letters. We should treat God’s name as sacred and holy.
One of the Ten Commandments states: “You shall not take the name of the Lord your God in vain, for the Lord will not leave him unpunished who takes His name in vain” (Ex. 20:7). In Jewish culture, God’s name was treated with great reverence, but we live in a society that doesn’t honor the Lord or His name. As Christians, we must be careful not to get swept up in the casualness or profanity with which many use the Lord’s name—and this includes the name of Jesus because as the Son of God, His name is also sacred and holy.
Taking the Lord’s name in vain includes more than just profanity. As Christians, we continually carry Christ’s name with us. Do we ever dishonor His name with our words, behavior, or attitudes? Let us repent and commit to glorifying and exalting His holy name with our mouths and our lives.
