Jesus really summed such things up in these words...
Joh 15:3 Now ye are clean through the word which I have spoken unto you.
Joh 15:4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.
Joh 15:5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.
Joh 15:6 If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.
Joh 15:7 If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
Salvation is wrought through abiding in the vine whereby the power of God literally flows through those whom abide.
Another way of describing this would be to liken ourselves to a light globe which must be screwed into the power source in order to shine. A light globe simply cannot shine apart from a necessary power source. Faith is where we plug ourselves in and grace is the power itself. Thus we are saved by grace through faith, we are saved via abiding in the Spirit of life in Jesus Christ.
In order to be saved an individual must lay aside all filthiness and superfluity of naughtiness (ie. rebellion to God, knowingly doing evil) and receive the implanted word (which cleans the soul) within. Thus true life (the kingdom of God within) is the result of hearing and doing just as Jesus taught.
Jas 1:21 Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.
Jas 1:22 But be ye doers of the word, and not hearers only, deceiving your own selves.
Mat 7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Mat 7:22 Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
Mat 7:23 And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
Mat 7:24 Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
Mat 7:25 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
Mat 7:26 And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand:
Mat 7:27 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell: and great was the fall of it.
