On the day of Pentecost, Peter declared, The God of Israel has made Jesus both Lord and Christ.  If Saul of Tarsus heard this, he would have been outraged.  For Saul, there was only one Lord, the God of Israel.  He could never say that a mere human was Lord in the same way.  And not just a human, but a crucified one! Only as the living Lord himself encountered Saul could he say that Jesus is Lord of all, and my Lord. 

Saul, known to us as Paul, confessed Jesus as Lord; but also declared the Spirit as Lord. “Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom (2 Corinthians 3: 17).  In the presence of the Lord, who is the Spirit, we also confess Jesus as Lord.  And in the same Spirit, we contemplate the Lord’s glory and are transformed into his likeness with ever-increasing glory (2 Corinthians 3: 18).  

Once we were in bondage under sin reigning over us in death, but the crucified Jesus disarmed and destroyed the dark powers that once ruled over us. And through him, we are transferred from the old dominion ruled by hostile powers to the new dominion of Christ.  And now, the Lord who is the Spirit enables us to remain free confessing Jesus as Lord and also contemplating his glory. so that we are transformed into his likeness.  Yes, we are truly free in the Spirit under the Lord Jesus. All because of the Lord who is the Spirit, for where the Spirit of the Lord is, there is freedom (2 Corinthians 3: 17).
