Or, put another way...

Christ was made flesh in order to destroy the devil -- ie, sin in the flesh: Heb 2:14; 9:26; Rom 8:3.
Sin is that which has the power of death, and sin comes from within: Rom 6:23; 7:13,20; 1Co 15:56.
The relationship of flesh and blood, sin, and the devil: Heb 2:14 (Christ partook of flesh and blood, in order that through his death, he might destroy the devil); Rom 8:3 (Christ was made in the likeness of sinful flesh, and died as an offering for sin, and so condemned sin in the flesh); Eph 2:15,16 (Christ, in his flesh, reconciled us by his death on the cross, and so slew the enmity which is in our flesh).
