For through him we both have access in one Spirit to the Father. (ESV)
Have you ever had a meeting with the President of the United States? Neither have I. How about a meeting with one of your favorite musicians? Maybe that's a little more likely, but still not a normal occurrence. Now, consider that fact that as believers in Jesus Christ we can have an intimate meeting at any time with the Creator of the Universe. Does that blow your mind? It should.
Paul says that through Jesus Christ we have access in the Holy Spirit to the Father. First of all, consider the fact that even the Jews could only have access to the Father by means of a high priest in the sacrificial system. The Gentiles had absolutely no access to God the Father. As Paul has established the Gentiles were without hope and without God in the world. Both Jews and Gentiles are unworthy to come to God in their own righteousness. But because we have been given the righteousness of Christ, we are granted access. What wonderful access that is!
 For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, “Abba! Father!”  The Spirit himself bears witness with our spirit that we are children of God, (ESV)
God's Spirit that we received is the Spirit of adoption as sons. Think of that. The access we have to the Father is as his son! In fact, this word "Abba" is an intimate word that means "daddy." Picture a child in his father's lap calling his father, Daddy. That is the kind of access we have.
Do you feel away from God? If you belong to him you have access to the Father. Intimate access. Family access. Spend some time with him today. He is your "Abba."
