Galatians 1:6 Meaning

4Who gave himself for our sins, that he might deliver us from this present evil world, according to the will of God and our Father:

5To whom be glory for ever and ever. Amen.

6I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:

7Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.

8But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
