Galatians:
1. Paul was authorized by Jesus to preach the gospel.
2. Someone was teaching that circumcision was necessary to become Christian and that the LAW OF MOSES had to be followed....all 613 laws.
3. Paul teaches here that the LAW OF MOSES...all 613 laws...DO NOT SAVE.
But only faith saves.
4. The civil and ceremonial laws were abolished.
The MORAL LAW (10 commandments) of God will NEVER be abolished.
In the letter to the Galatians, Paul sets out many rules that Christians are to follow:
Galatians 5:16-21
16But I say, walk by the Spirit, and you will not carry out the desire of the flesh.
17For the flesh sets its desire against the Spirit, and the Spirit against the flesh; for these are in opposition to one another, so that you may not do the things that you please.
18But if you are led by the Spirit, you are not under the Law.
19Now the deeds of the flesh are evident, which are: immorality, impurity, sensuality,
20idolatry, sorcery, enmities, strife, jealousy, outbursts of anger, disputes, dissensions, factions, 21envying, drunkenness, carousing, and things like these, of which I forewarn you, just as I have forewarned you, that those who practice such things will not inherit the kingdom of God.
22But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness,
23gentleness, self-control; against such things there is no law. 24Now those who belong to Christ Jesus have crucified the flesh with its passions and desires.
Does that sound to you like Jesus "did it all" on the cross...
or does it sound like Jesus did HIS part and now we have to do OURS....
(there's more BTW,,,right there in the letter to the Galatians that you so love)
