John is very positive about what will be the expression of those who are born of God, of those who are abiding in Christ: "And hereby we know that we know Him, if we keep His commandments" (1 John 2:3). "He that saith he abideth in Him ought himself also to walk even as He walked" (2:6). "If ye know that He is righteous, ye know that everyone also that doeth righteousness is begotten of Him" (2:29). "Whosoever abideth in Him sinneth not; whosoever sinneth hath not seen Him, neither knoweth Him" (3:6). "We know that we have passed out of death into life, because we love the brethren. He that loveth not abideth in death" (3:14).
"And He that keepeth His commandments abideth in Him, and He in him, and hereby we know that He abideth in us, by the Spirit which He gave us" (3:24). "Hereby we know that we abide in Him and He in us, because He hath given us of His Spirit" (4:13). "For whatsoever is begotten of God sinneth not, but he that was begotten of God keepeth himself, and the evil one toucheth him not" (5:18). "We know that we are of God, and the whole world lieth in the evil one" (5:19).
All of the above scriptures tell us how complete a work has been done by God, pertaining to sin and our relationship with Him. These scriptures will bring only condemnation unless we are abiding in Christ. God's Word cannot find fulfillment in us in any way other than union with God by the Spirit.
Faith finds its true meaning in union with Christ. If we have the life of God, we will not continue to sin or move outside of our union with God. We are not trying, but trusting. We are not doing "the best we can," for that misses the mark every time. The Christian is living the life of God, moving in union with the indwelling Spirit. This is our relationship with God. The one necessary ingredient is the life of God indwelling us by the Spirit. Faith moves into God and dwells there by faith.
