Sinners need to forsake their ways and thoughts (actions and attitudes, Isaiah 55:7) because they are not God"s ways and thoughts. God"s way is forgiveness and His thoughts are compassionate ( Isaiah 55:7), as far different from those of sinners as the heavens are higher than the earth. Sinners must make a break with their thoughts and ways to have fellowship with a holy God. The Servant"s work makes relationship with a holy God possible, but our work, having appropriated the Servant"s work by faith, makes intimate fellowship with a holy God possible.
