Isaiah used highly figurative language to describe the Savior’s battle against evil represented by Edom, Israel’s ancient and bitter enemy. He was pictured as having the blood of sinners like grape stains from the winepress upon His garments. Only He was able to atone for their sins with His own blood.
Israel was chosen many years earlier to be God’s people. Many times, their faithfulness to Him wavered as they turned from Him and fell into the various sins of the day. He in response, turned His back as an enemy upon Israel. As they would repent and return to Him, He in His mercy would receive them back into His arms.
It is easy to blame God for our weaknesses and ask, “Why have You made us stray from Your ways, and hardened our heart from Your fear?” He could keep us from sinning, but that is not His plan. He has given us the freedom to serve Him or Satan.
