Galatians 3:1-18 Is Christianity by Faith or Legalism?

There are hundreds of so-called "Christian" denominations across the world today.  And there are major branches off of the original followers of Jesus Christ.  We have Orthodox, Catholic, Protestant, and Charismatic "Christianity."  So how can a person know where to find the truth?  Well, as I said to someone just recently, "There are two huge heresies that should cause you to run from any church.  One is if they falsely teach who God is.  God is Creator, eternal, Spiritual, and Triune in nature.  He was never a man.
And the second teaching that should make you run from any church, is if they teach that you have to "be a good person" to be saved.  Scripture teaches that Salvation is a gift from God, through Jesus, given to us because of His love, and in response to our belief.
We don't get it by being "good" or following certain rituals.  We don't keep it by being "good."  We don't lose it by sinning.  We don't earn it.  We don't buy our way into heaven.
If your church teaches any of that...run...to a church that teaches the gospel.
That's Paul's message to the Galatians.
