The understanding of what Jesus experienced when He felt our sins and the effect of sin on Himself from the garden to the cross has an interesting application to our santification. He not only received the legal penalty, but during that time He actually felt and experienced in full within His emotions, feelings and sensations everything that we feel, sense, experience when we suffer in sin, shame, fear and guilt.
The amazing flip side of this is that we are to live our lives experiencing in exactly the same way and to the same degree the feelings, emotions and reality of His perfect righteousness that has no causative within ourselves other than our belief in His provision. We are asked, even expected, to indulge ourselves by means of trust in God's promises, to actually experience in every way the daily life that Jesus lived as a perfect human vicariously including His emotions, feelings and sensations. To the same degree that He experienced my sin I am expected and privileged to experience His perfection.
By the same principle, just as He never shoe to sin and therefore had no trace of cause in Himself for the effects of sin that He suffered; just so I am not to choose to be righteous in any respect as a cause for the experience of and effects of being a righteous being. If I believe that even one thread of my righteous “robe” is of my own making then by the law of equation I am implying that maybe at least one thread of Jesus' suffering and punishment was caused by some little sin He committed.
