It is our choice to align ourselves with His strength that makes the reality of the Christian faith come alive (2 Cor 5:15). If we truly want to experience and live the promises that God has given to us, He tells us to cleanse ourselves from the defilement that blocks us (2 Corinthians 7:1).
It is our responsibility to rid ourselves of the filthiness in both our flesh and our spirit so that we are able to live out His admonition for us to be holy as He is holy (1 Peter 1:15, 16).
