And He saw that there was no man

                                                     

The first man, Adam, sinned, bringing separation between God and man. (Romans 5:12).

"But your iniquities have separated between you and your God, and your sins have hid his face from you..." - Isaiah 59:2

God saw the sad condition of man in his sinful state. He looked and saw there was no human that could save mankind from his wretched condition. So God Himself, His right arm of power, reached out and redeemed man from his bondage to sin. (Acts 20:28).

"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  

"Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil; and deliver them who through fear of death were all their lifetime subject to bondage." - Hebrews 2:14-15

God’s arm is a symbol of the body He made for Himself to dwell among men. It represents power because by His body He paid the price of sin by death to reconcile man back to Himself.

"Who hath believed our report? and to whom is the arm of the LORD revealed? ... because he hath poured out his soul unto death; and he bare the sin of many..." - Isaiah 53:1, 12

There would be no more division. God brought peace. That is why when Jesus was born, the Father revealed in flesh, He was called the Prince of Peace. (Isaiah 9:6). He came in power to bring man back to Himself.

"And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven." - Colossians 1:20

"And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled in the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight: if ye continue in the faith grounded and settled, and be not moved away from the hope of the gospel…" - Colossians 1:21-23 (Acts 2:38).

"To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them..." - 2 Corinthians 5:19
