Commentaries:
God bears long and is slow to anger. Longsuffering is proof of God's goodness, faithfulness, and His desire to grant us salvation. Romans 2:4 describes God as forbearing and longsuffering. Forbearance is refraining from the enforcement of something that is due like a debt, right, or obligation. Longsuffering differs slightly in that its emphasis is on temperament.
