He was God yet He suffered. he experienced weakness, a life filled "with fervente cries and tears" [Heb. 5:7]. He knew firsthand rejection and betrayal, poverty and abuse, disappointment and despair, bereavement, torture and death. And so he is "able to empathize with our weaknesses" for He "has been tempted in every way, just as we are- yet without sin" [Heb. 4:15]. On the cross He went beyond even the worst human suffering and experienced cosmic rejection and a pain that exceeds ours as infinitely as His knowledge and power exceeds ours. There is no greater agony then the loss of a love relationship. we can not imagine, however, what it would be like to lose not just a human relationship that has lasted from some years but the infinitive love of the Father that Jesus had from all eternity. The separation would have been infinitely unbearable. ans so Jesus experienced Godforsakeness itself on the cross when He cried out "My God, my God! Why have You forsaken me?"
Here we see the ultimate strenght- a Gos who is strong enough to voluntarily became weak and plunge Himself into vulnerability and darkness out of love for us. And here we see the greatest possible glory- the willingness to lay aside all His glory out of love for us.
