However, if we [apostles] or even an angel [claiming to be] from heaven were to preach any other "gospel" than the one we have [already] preached to you, let that person be cut off from God's [salvation].

I am afraid for you, [i.e., for your spiritual safety], that possibly I may have spent a lot of effort on your behalf for nothing.

But, if you are led by [what] the Holy Spirit [wants you to do], you are not under [obligation to meet the requirements of] the law of Moses.

But let each person test his own accomplishments so that he can determine if he should get credit for them or if his neighbor should.

For each person should shoulder the responsibility of his own work load.
