The Father is Spirit. Throughout the Old Testament, God used metaphors to describe His power, redemption, salvation, omnipresence, acceptance, mercy, judgement, and authority.

These metaphors include the arm, eyes, ears, nose, face, back, and hand. God used these metaphors so we could better understand and relate to God, as we are physical beings.

God’s arm is a metaphor of His power, redemption, and salvation. The Bible says God redeemed the children of Israel from Egyptian bondage with His arm.

"Wherefore say unto the children of Israel, I am the LORD, and I will bring you out from under the burdens of the Egyptians, and I will rid you out of their bondage, and I will redeem you with a stretched out arm, and with great judgments:" - Exodus 6:6 KJV (Deuteronomy 9:29, Psalm 44:3)

All of humanity needed a redeemer. More than redemption from Egyptian bondage, mankind needed redemption from the bondage of sin and death. (Hebrews 2:14-15)

The Bible says that God saw there was no man that could redeem mankind from sin. Why? Because all are born in sin. Only God Himself – our Heavenly Father – could step in and redeem mankind from sin and death. Only our Heavenly Father could be our Savior. The Bible describes God’s salvation as His arm.

"And he saw that there was no man, and wondered that there was no intercessor: therefore his arm brought salvation unto him; and his righteousness, it sustained him." - Isaiah 59:16 KJV

Isaiah prophesied of the revealing of God’s arm. Isaiah begins his prophecy with the statement, "Who hath believed our report? and to whom is the arm of the LORD revealed?” The rest of the chapter describes in detail in advance of the now familiar life, death, burial, and resurrection of Christ – foretold through prophecy by Isaiah hundreds of years before Christ’s birth. (John 12:37-41, Romans 10:13-16)

"Who hath believed our report? and to whom is the arm of the LORD revealed? ... He is despised and rejected of men; a man of sorrows, and acquainted with grief... But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed...when thou shalt make his soul an offering for sin, he shall see his seed, he shall prolong his days…by his knowledge shall my righteous servant justify many; for he shall bear their iniquities…because he hath poured out his soul unto death…and he bare the sin of many..." - Isaiah 53:1, 3, 5, 10-12 KJV

It is clear the arm of the LORD is Christ – the Father in a human body. He is our Savior and Redeemer.

"The LORD hath made bare his holy arm in the eyes of all the nations; and all the ends of the earth shall see the salvation of our God." - Isaiah 52:10 KJV
