Passage
And Jesus answering said to them, `For the stiffness of your heart he wrote you this command,
And Jesus answering said to them, `For the stiffness of your heart he wrote you this command,
Mark 10:3 and he answering said to them, `What did Moses command you?'
Mark 10:4 and they said, `Moses suffered to write a bill of divorce, and to put away.'
Mark 10:5 And Jesus answering said to them, `For the stiffness of your heart he wrote you this command,
Mark 10:6 but from the beginning of the creation, a male and a female God did make them;
Mark 10:7 on this account shall a man leave his father and mother, and shall cleave unto his wife,
The verse centers on "jesus", "answering", "said", "stiffness", "heart", "wrote", and "command". It is saying that the verse draws attention to "jesus" and "answering", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "and they said Moses suffered to write..." into verse 6's "but from the beginning of the creation...", so "jesus" and "answering" belong inside that flow. In Mark context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "jesus" and "answering" with trust shaped by these words, not by a vague optimism outside the passage.
