The sacrifice of Jesus is complete but “our appropriation of the benefits” is progressive.
The basis of every benefit we seek from God is what was done by Jesus on the cross.
On the cross, a divine exchange took place. The cross is Satan’s only point of defeat.
Our weapon against the enemy is what happened on the cross.
Revelation 12:11 “And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death.”
