God arrived at Calvary - not in light, but in darkness. He showed up to unleash judgment, not in the eschatological sense in the future against the ungodly, but in the soteriological sense against the godly One. What is really going on at Calvary, folks – and this is where you go deeper with the understanding of it – it’s beyond the physical suffering, it’s beyond the sacrifice of Christ. What’s happening here is divine wrath is being poured out in its final form. Eternal wrath is about to be released and the darkness is everywhere. You could say it another way. God brought hell to Jerusalem that day.
