Charles H. Spurgeon on Psalms 103:8

Merciful and gracious, slow to stager and plenteous in mercy. O my soul, bere are four properties spoken of to be in God, and are all so necessary, that we could not miss one of them. If he were not "merciful" we could hope for no pardon; and if he were no more but merciful we could hope for no more but pardon; but when besides his being merciful he is also "gracious, "this gives us a further hope, a hope of a donative; and then it will not be what we are worthy to receive, but what it is fit for him to give. If he were not "slow to anger" we could expect no patience; but when besides his slowness to anger he is also "full of compassion; "this makes us expect he will be the good Samaritan, and not only bind up our wounds, but take care also for our further curing. What though he chide and be angry for a time; it is but our being patient a while with him, as he a long time hath been patient with us. Sir R. Baker.
