"Let the redeamed say so, whom he has redeemed from the hand of the enemy"
I encourage you to watch Dr. Larry Ollison, delivering a message of redemption, anointing and authority in Receive your Healing.
The Bible instructs us to say with our mouths that we are redeemed.
When the enemy tries to put the curse on you, say to the enemy, I am redeemed from the curse of the Law. (Deuteronomy 28:61)
According to the verse above "all sickness is the curse of the Law" and we (Christians) are redeemed from the curse of the Law ( Galatians 3:13).
Let the redeemed of the Lord say so!.
