Only Christ can rightly use the name of the Lord without it being in vain, as He embodies God's character and has intimate knowledge of Him.
According to the sermon, only Jesus Christ has the right to take the name of the Lord not in vain. Christ, as the Son of God, is fully God and fully man, making Him uniquely worthy to bear the name of the Lord. He possesses the perfect character that reflects God's holiness, righteousness, and justice. For believers, it is through our union with Christ that we can call upon God's name, as we are made His children and thus partake in the relationship and privilege that come with that status. Outside of Christ, we are unworthy and should not approach God, but in Christ, we are welcomed and empowered to call upon Him.
