After the final judgment, the Lord will divide the sheep from the goats. The sheep are placed on his right hand, and the goats are placed on his left. As the Lord has said, My sheep hear my voice, and I know them, and they follow me (Jn 10:27). As Benjamin explains, [the righteous] know the voice by which [they] shall be called (v. 12). The goats on the left don't know the voice of the good shepherd, For how knoweth a man the master whom he has not served (v. 13). Therefore, they must be called by some other name (v. 11) because they are not worthy of the name of Christ.
Apparently, it is always better to be on the right hand of God. "The right hand denotes power or strength. The scripture generally imputes to God's right hand all the effects of his omnipotence, Ex 15:6, Ps 17:7; 20:6; 44:3." (Reynolds and Sjodahl, Commentary on the Book of Mormon, vol. 2, p. 80) This is the eternal position of the Son of Man, who said to the Sanhedrin after his unlawful arrest, Hereafter shall the Son of man sit on the right hand of the power of God (Lu 22:69).
