Our whole body must be presented to God....
The HEAD - consecrate my understanding and thoughts entirely to the service of God, under His control - obedient to Christ.
The EYE - turned away from the world and it's vanities and desires to see or not to see according to God's will.
The EAR - consecrated to the Lord - is not to listen to language or conversation that pleases my flesh BUT attentive to the voices which the Lord sends to me.
The MOUTH - must be consecrated to the Lord - not to speak anything except what is according to His will and to His glory.- (Andrew Murray)
All must be sanctified and purified for God by the cross. (that we must choose to carry)
