Christ is not divided. To whatever extent Christians have disagreements amongst themselves - it is carnal, not Spiritual.
That could very well be; but it could also be from following the evil spirit who appears as the Angel of Light.
But he that glorieth, let him glory in the Lord." -- 2 Corinthians 10:17
My brethren, do not hold your faith in our glorious Lord Jesus Christ with an attitude of personal favoritism [James 2:1]
For if there come unto your assembly a man with a gold ring, in goodly apparel, and there come in also a poor man in vile raiment; And ye have respect to him that weareth the gay clothing, and say unto him, Sit thou here in a good place; and say to the poor, Stand thou there, or sit here under my footstool: Are ye not then partial in yourselves, and are become judges of evil thoughts?
Hearken, my beloved brethren, Hath not God chosen the poor of this world rich in faith, and heirs of the kingdom which he hath promised to them that love him? But ye have despised the poor. Do not rich men oppress you, and draw you before the judgment seats? Do not they blaspheme that worthy name by the which ye are called?
If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well: But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors.
For whosoever shall keep the whole law, and yet offend in one [point], he is guilty of all. - James 2:1-10
Again, the bottom line is this: if we try to live by the Law, God will let us and we will fail. The ones who never heard of Christ or the Law will be judged by the law written in their hearts. The ones who are in Christ Jesus are free from the Law. No one can be “good enough” – if even one could, then Christ died for nothing.
Maranatha, Jesus!
