Mark 3:27

3:27 But no one is able to enter a strong man’s ¹  house and steal his property unless he first ties up the strong man. Then he can thoroughly plunder his house. ² 

Mark 9:12

9:12 He said to them, “Elijah does indeed come first, and restores all things. And why is it written that the Son of Man must suffer many things and be despised?

¹ sn The strong man here pictures Satan.

² sn Some see the imagery here as similar to Eph 4:7-10, although no opponents are explicitly named in that passage. Jesus has the victory over Satan. Jesus’ acts of healing mean that the war is being won and the kingdom is coming.
