It is common for people in our modern culture to throw around the name of Jesus and to use it as a curse word. But misusing the name of the Lord Jesus Christ is the height of foolishness and stupidity. These people do not honor or respect the Lord. They are actually expressing their hatred for him.
Why is there all this hatred for Jesus? It is because people love the darkness rather than the light. Jesus exposes them as sinners who stand guilty before a holy God(see John 3:19-21). As guilty sinners they face the wrath of God and eternity in hell. Yet these people express hatred for the only hope of salvation they have, namely Christ Jesus himself.
Jesus is the name above all names, deserving the utmost respect and honor(see Philippians 2:5-11). Jesus is the Christ (or Messiah), the only, unique Son of God. He came to save his people from their sins (Matthew 1:21). Christ died on the cross to pay for the sins of his people, to turn away the wrath of God from them. He was raised from the dead victorious over sin, death, and the devil. Jesus lived a perfect life without sin enabling him to be our perfect substitute. Christ took the sins of his people on himself and his righteousness is credited to us (2 Corinthians 5:21).
We must repent of our sin and place our faith in Christ alone for salvation. Jesus is the only way to heaven (John 14:6, Acts 4:12).
(John 20:31)"but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name." (ESV)
