Until Christ is formed in you

Galatians 4:12-20
I plead with you, brothers, become like me, for I became like you. You have done me no wrong. Have I now become your enemy by telling you the truth?
Those people are zealous to win you over, but for no good. What they want is to alienate(離間)you from us.
My dear children, for whom I am again in the pains of childbirth, until Christ is formed in you, how I wish I could be with you now and change my tone, because I am perplexed(困惑)about you.
Why?
The Galatians had responded eagerly to Paul's preaching. What happened to make them change?
Paul's loving, anxious concern is palpable in this passage. Can they really want to throw their freedom away?
Zealous is good for the right things, but it is wrong for no good.
God hopes all Christian that Christ is formed in us. Have faith that won't be shaken by any others.
How?
I will not be shaken, because Jesus is with me, these inside me is greater than outside.
