Yes curses do exist, but the blood of Jesus has been granted to us for redemption from all the curses and we receive deliverance from every curse by putting faith in Jesus' resurrection.

The Spirit of the Lord is upon Me, Because He has Anointed Me To preach the gospel to the poor; He has sent Me to heal the brokenhearted, To proclaim liberty to the captives And recovery of sight to the blind, To set at liberty those who are oppressed.
