What is the first Adam said to be in Paul's contrast with Christ?
In the contrast with Christ, the first Adam is said to have been made “a living soul” by virtue of creation, existing in perfect fellowship with his Maker. The second Adam, the man Christ Jesus, is presented as a life-giving spirit, the God-man. This contrasts creation and perfect fellowship with the life-giving spirit.
Les teaches that the first Adam was made a living soul by virtue of creation, in perfect fellowship with his Maker; the Lord could walk with him in the cool of the day, with nothing between them. Perfect fellowship. Then the second Adam was brought on the scene as a life-giving spirit, in the person of the man Christ Jesus, the God-man. This is the contrast: the first Adam relates to creation and fellowship with God, while the second Adam is the life-giving spirit in Christ Jesus.
