I'm not sure if receiving the Spirit of Christ is the same as being adopted by the Father in Romans 9; but if one wishes to be adopted into the family of God, according to 2 Corinthians 6:17-18 it looks like we need to leave our worldly goods and lifestyle behind us.
As most of us never attain this level of discipleship, I then think that to receive the Spirit of Christ may not be as demanding.
Yes , recieving the Spirit of Christ is being finally adopted by the Father . And it happens the same way, " by Faith ".
Salvation is by Grace , through Faith .
Luigi , I don't think you realize how close you are to the truth .
At this point of the Salvation journey , when we have yet to receive the Spirit of Christ , and as such Christ , His Word , and His promises are not ours yet , how does one move forward in the process without violating God and His Word ?
The answer is simple , " by Faith " ! But explaining this is a little more difficult .
Did you know that the Greek has two words for Faith ? The noun " pistis " and the corresponding verb " pisteuo " Did you also know. , That pistis is where we get our English word , the noun , " Faith " , and the corresponding verb " pisteuo" could not be translated into the English language , because the English language has no verb form of the noun Faith .
Here is the exact definition of " pisteuo " from the Vines Greek dictionary . " A personal surrender to Him , and a life inspired by such surrender ."
This is the third step , but is done outside of God and His Word . This first act of faithing or pisteuo is simply done to be accepted as genuone by Christ . Still no Spirit of Christ yet , and Christ , His Word , and promises there in are not ours yet either .
If Christ deems our surrendered life genuine , we move forward to step 4 , any thoughts on what that would be ?
