Galatians 2:20

I have been crucified with Christ (that is, in Him I have shared His crucifixion); it is no longer I who live, but Christ lives in me. The life I now live in the body I live by faith, (by adhering to, relying on, and completely trusting) in the son of God, who loved me and gave Himself up for me.

Jesus conquered death, sickness, fear, lack, hell, and the curse when He was crucified on the cross. When we are saved and born again, we have the connection to all that Jesus did living inside of us. We must trust and focus on Jesus and believe in His completed works. It is finished, and our redemption is through the shed blood of Jesus, who is the substitute for our sins.
