Which is easier, to say to the paralytic, ‘Your sins are forgiven,’ or to say, ‘Rise, take up your bed and walk’? But that you may know that the Son of Man has authority on earth to forgive sins”—he said to the paralytic—“I say to you, rise, pick up your bed, and go home.”
Mark 2:9-11 ESV
In reading through Mark using several study Bibles and a couple of commentaries when necessary, the comment on this passage in the ESV Study Bible is very helpful.
Mark 2:9–11 Which is easier … ? On the surface, of course, it is easier to say the words, “Your sins are forgiven,” because that is something invisible and impossible to disprove. But it is harder to say, “take up your bed and walk” because, if the man does not get up, the one who said the words will be shown to have no authority to heal. On a deeper level, however, it is harder to forgive sins, because only God can forgive sins—at the cost of Christ’s death on the cross. The logic here is that, since Jesus can do the visible miracle (heal the paralytic), this is evidence that he also has the power to do the invisible miracle (forgive sins).
I’ve been using up to seven study Bibles. All of them are available to me online except the paper version of The MacArthur Study Bible (NASB), which I have found to be the most helpful after using it and others while reading 1 Timothy through Revelation.
You can find the Reformation Study Bible for free at BibleGateway, along with previews of many others, along with some commentaries, and the HCSB Study Bible on their own site. Go to the Library link on the left and find it within the book list. Let me know if there are others you’re familiar with.
