We are sinners (enemies of God) by our personality (Romans 5:19), sons (children) of God by Jesus’ purchase of our lives with his own blood (Galatians 4:4,5; Acts 20:28), and servants by the provisions (gifts) that God has given unto each one of us (Romans 12:6).

What title best describes you and me today? A sinner, a son/daughter or a servant?
If you are an unrepented sinner, believe in the Lord Jesus Christ today. If you have believed i.e., you are a son/daughter, then live life like your life does not belong to you because it has been purchased by God (Jesus Christ) for God and this means that we live as servants according to the proportion of our faith.

Romans 5:19 (KJV)
19 For as by one man’s disobedience many were made sinners, so by the obedience of one shall many be made righteous.

Galatians 4:4,5 (KJV)
But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
To redeem them that were under the law, that we might receive the adoption of sons.

Acts 20:28 (KJV)
28 Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood. 

Romans 12:6 (KJV)
Having then gifts differing according to the grace that is given to us, whether prophecy, let us prophesy according to the proportion of faith;
