Why is it important to know God's name?
Joel 2:32 "And everyone who calls on the name of "YHWH" will be saved..."- This verse is also referenced in the Greek scriptures(New Testament) at Acts 2:21 and Romans 10:13.
Does that mean that being a Christian is not important, as long as I know the name Jehovah and call on Him and pray to Him?
Romans 10:8............“The word is near you, in your mouth and in your heart” (that is, the word of faith that we proclaim); 9 because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. 10 For with the heart one believes and is justified, and with the mouth one confesses and is saved. 11 For the Scripture says, “Everyone who believes in him will not be put to shame.” 12 For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. 13 For “everyone who calls on the name of the Lord will be saved.”
14 How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching?
In the above passage it does say "everyone who calls on the name of the Lord will be saved" but it says that in the middle of a passage about spreading the gospel about Jesus and calling on the name of Jesus. Do you think it might be actually telling us that Jesus is the name we are to call on, that Jesus is YHWH? It certainly looks that way.
