But here is what John Piper says:
A profound understanding and fear of God’s wrath is exactly what many need, because without it, the gospel is diluted down to mere human relations and loses its biblical glory... because you have never really tasted what it is like to see an infinitely greater wrath overcome by grace, namely, God’s wrath against you. (This Momentary Marriage)
Simply, as I ponder God's wrath against people in the Bible and I think about God's wrath against His Son - and I think about the wrath that I deserve, I am terrified! But then I flee to the cross and think about how the cup of God's wrath was pured out for me, I am compelled to think about the One who took that wrath for me. Suddenly, that word friendship become wholly inadequate!
