God cannot suffer - at least not as we do. It has some roots in Greek philosophy: if God is a perfect being, suffering would reduce that perfection, so God cannot suffer. More thoughtful theologians take the phrase in the sense of one of the confessions of faith that talks of God as being "without parts or passions" - he is not physical as we are, and not subject to "passions" in the sense of uncontrollable emotions that can take charge of us at times. God is not "emotional," if that word is used as some kind of weakness.
Christopher J. H. WrightWe tend to speak of sin in very personal and individual terms. Jeremiah does not downplay that, but he also sees how a whole society can be bound up in the tentacles of sin, in the assumptions that everybody around you makes, about how it becomes easier to sin than not to, and how we can become so confused and contradictory in our reactions, when sin is pointed out.
Christopher J. H. WrightThe Bible itself does not seem too bothered by the idea that talking of God suffering might in any way diminish God, or detract from his perfection. On the contrary, the Bible seems to revel in the richness of describing God in ways that reflect our own human realities.
Christopher J. H. WrightGod has made us humans in God's own image. So therefore the highest way to talk about God is by some kind of analogy with ourselves. So, naturally, if we who are finite and sinful suffer in multiple ways because of sin and evil and the horrible things that happen in our world, how much more does God, who is infinite, sinless, and knows the totality of all that happens to everybody, suffer pain and heartache at the suffering of his human and non-human creation - and be angry at all that causes it?
Christopher J. H. Wright"It is finished" means that Jesus had accomplished all that God's mission had sent him to do. It did not merely mean that his life was over like, "I'm finished". It was a statement of achievement of purpose - God's purpose to deal with sin and guilt, to defeat all the powers of evil, to bring about the reconciliation of enemies, to defeat death itself, and to accomplish the reconciliation and liberation of the whole creation.
