"We all have a role in the Body of Christ!" But we have to accept our role and responsibilities
Romans 1:1 Paul, a servant of Jesus Christ, called to be an apostle, separated unto the gospel of God,
Paul a one time murderer, accuser and destroyer of the church, now sits at a crossroad in the acceptance of Christ, the mission and his role.
Paul in Romans 1:1 makes his choice. First he acknowledges his acceptance of the mission by proclaiming, he is here to serve (A Servant). Second he acknowledges his position in the ministry (An Apostle), which signifies the ministry calling for him. Lastly, he acknowledges, by his acceptance of the mission and the ministry, God has set him apart or Sanctified him for the Work unto him.
This is not just for Paul, but each of us, it does not matter how we started, but if we are willing to accept the mission and the ministry. Because of this, we can all celebrate knowing, it is nothing that you have to do to get ready for God, but that God is already ready for you.
That is enough to make you want to jump and down and give "Praises to the Lord."
