God fights the enemies in our way with His right hand, and He guides us along like the sheep of His flock with His left. It is as the right hand releases the bow to power the shot, while the left hand guides the arrow (those hand uses are in several psalms). Writing in Hebrew covers the line as we write, just as God's salvation (Jesus) covers the sins of our past as we journey into His mercy.
well when it comes to right and left hand, I'd say the Lord Jesus knows best what is meant:
Mat 25:31 When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:
Mat 25:32 And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:
Mat 25:33 And he shall set the sheep on his right hand, but the goats on the left.
Mat 25:34 Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world:
Mat 25:35 For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in:
Mat 25:36 Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me.
Mat 25:37 Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink?
Mat 25:38 When saw we thee a stranger, and took thee in? or naked, and clothed thee?
Mat 25:39 Or when saw we thee sick, or in prison, and came unto thee?
Mat 25:40 And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.
Mat 25:41 Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:
Jesus sets at the Right Hand of Power, and not the left, for a reason.
