Gal 5:13-15

Galatians 5:13-15
King James Version (KJV)
13 For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another.
14 For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself.
15 But if ye bite and devour one another, take heed that ye be not consumed one of another.

Galatians 5:13-15
Holman Christian Standard Bible (HCSB)
13 For you were called to be free, brothers; only don’t use this freedom as an opportunity for the flesh, but serve one another through love. 14 For the entire law is fulfilled in one statement: Love your neighbor as yourself. 15 But if you bite and devour one another, watch out, or you will be consumed by one another.

These are my thoughts, please share yours.
13 We are free from the law and the burden of sin as well as judgment all because we have Christ’s blood covering ours sins. We are able to fight our flesh because we have Him leading us thru a walk in faith by His side. We should serve each other thru love. The love we show should be the same love His imparts to us.
14 The law is not just the tem commandments but the whole first five books of the bible. There are many laws written in these books also known as the Torah. This is a commandment given from the Lord Jesus Himself. To love is to not do anything sinful against them. This is also a common part of the law that the Pharisees of Jesus day did not obey they did not love but, the world will not love others as their selves this only comes after receiving His love.
15 Hate causes destruction and separates people. Hate does no good at all but always leads to evil. The devil wants us to fall into hate where we can not show His love thru our lives.
For ye, brethren, were called for freedom; only use not your freedom for an occasion to the flesh, but through love be servants one to another.

The Law created a sense of guilt and helplessness. It kept the saint in an immature spiritual condition. Paul used the Greek tutor motif and said the law was that tutor or more specifically the home school pedigog.

A pedigog had total authority of the children in the Greek home - equal to the father. The tutor was dismissed after the student reached adulthood and the token of the adulthood was signified by the father placing upon the student the adult toga. Paul says Christ is that toga, that spiritual adulthood and maturity.

14 For the whole law is fulfilled in one word, even in this: Thou shalt love thy neighbor as thyself.

Evidently love was the highest state of spirituality under the Mosaic Law. Because sins were multiplied by the flesh's inability to keep the Law it should have produced humility. Jesus in His exposition of the Law said blessed are the merciful, and blessed are the meek and poor in spirit. Poor in that they were remorseful of their sins and meek meaning a quiet confidence in God. The Law was unable to produce personal holiness and personal righteousness. Christ's cross does bring these things and we should be careful to maintain a humble an quiet confidence toward God and love toward one another, serving one another with the Gifts.

15 But if ye bite and devour one another, take heed that ye be not consumed one of another.

Those who failed to see the purpose of the Law failed to be merciful and put confidence in themselves rather than being meek. They became prideful rather than of a broken spirit and took The Lord's name in vain.

16 But I say, Walk by the Spirit, and ye shall not fulfil the lust of the flesh

Building on the theme of living sanctified holy lives by walking in the spirit we can reach maturity. We walk maturely by faith and not according to the Law that the flesh could not keep. To fall from grace means to revert back to trying to gain the sanctified holy life thru keeping the Mosaic Law or any other laws that are made up by religions to attain personal righteousness.
We have been declared righteous and by faith we are to reckon it as so and live our lives in faith. Faith in the imputed righteousness of Christ.
