We will finally see the events of history are culminating in a great, final effort to reach us. The "anger" (caused by our rejection of what was offered) is now "turned away." Actually, it wasn't really anger. It was our refusal to accept what was offered. We regard it as anger when we can't get from God what He offers on condition of obedience. We disobey, lose the blessing, and think God is angry with us. It is our perception, based upon our selfish view of everything, that He is angry. We want our God to bless us, and we want to be able to offend Him, too. But since He "cannot look upon sin with the least degree of allowance," we are asking the impossible when we want Him to accompany us as we trample through and among the filth He asks us to avoid.
As we finally repent and decide to do as He asks, His Spirit returns. We then rejoice and say His anger is turned away, and now He is there to comfort us. All along He was willing to do so, but we are difficult companions. As we reform and the Spirit returns to us, we take great comfort in finally receiving what He offered all along.
