Faith is a living work necessary to commune between two minds . Christianity is it in respect to the mind of Christ revealed by the scriptures, prophecy. We are lovingly commanded to let His mind be in us by faith and shows us how..
Trying to divide the faith of Christ that he exercised towards the creature from the work of Christ's labor or love seems to be were many differ? The idea of separating faith from works can only lead to blaspheming the one Holy name of God.
The phrase in Hebrews 4 "mixing faith in them that heard it" is the key representing those that who did believe God. God giving them rest and comfort making their hearts soft. Again "mixing faith" using the temporal seen to reveal the unseen eternal hid .(2 Corinthian 4:18) It can help our anxieties in our hour of need.
Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it. For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it. For we which have believed do enter into rest, as he said, As I have sworn in my wrath, if they shall enter into my rest: although the works were finished from the foundation of the world. For he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works. And in this place again, If they shall enter into my rest. Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief: ( Did not mix faith) Again, he limiteth a certain day, saying in David, To day, after so long a time; as it is said, To day if ye will hear his voice, harden not your hearts..Hebrews 4:1-8
